 # Contributing
 
-## Building
+Here are some guidelines that should help to start contributing to the project.
 
-You need either [Docker](https://github.com/docker/docker) and `make` (Method 1), or `go` (Method 2) in order to build Traefik.
-For changes to its dependencies, the `dep` dependency management tool is required.
+- [Submitting pull Requests](https://doc.traefik.io/traefik/contributing/submitting-pull-requests/)
+- [Submitting issues](https://doc.traefik.io/traefik/contributing/submitting-issues/)
+- [Submitting security issues](https://doc.traefik.io/traefik/contributing/submitting-security-issues/)

+- [Triage Process](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md)
 
-### Method 1: Using `Docker` and `Makefile`
-
-You need to run the `binary` target. This will create binaries for Linux platform in the `dist` folder.
-
-```bash
-$ make binary
-docker build -t "traefik-dev:no-more-godep-ever" -f build.Dockerfile .
-Sending build context to Docker daemon 295.3 MB
-Step 0 : FROM golang:1.9-alpine
- ---> 8c6473912976
-Step 1 : RUN go get github.com/golang/dep/cmd/dep
-[...]
-docker run --rm  -v "/var/run/docker.sock:/var/run/docker.sock" -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/user/go/src/github.com/containous/traefik/"dist":/go/src/github.com/containous/traefik/"dist"" "traefik-dev:no-more-godep-ever" ./script/make.sh generate binary
----> Making bundle: generate (in .)
-removed 'gen.go'
-
----> Making bundle: binary (in .)
-
-$ ls dist/
-traefik*
-```
-
-### Method 2: Using `go`
-
-##### Setting up your `go` environment
-
-- You need `go` v1.9+
-- It is recommended you clone Træfik into a directory like `~/go/src/github.com/containous/traefik` (This is the official golang workspace hierarchy, and will allow dependencies to resolve properly)
-- Set your `GOPATH` and `PATH` variable to be set to `~/go` via:
-
-```bash
-export GOPATH=~/go
-export PATH=$PATH:$GOPATH/bin
-```
-
-> Note: You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
-
-- Verify your environment is setup properly by running `$ go env`.  Depending on your OS and environment you should see output similar to:
-
-```bash
-GOARCH="amd64"
-GOBIN=""
-GOEXE=""
-GOHOSTARCH="amd64"
-GOHOSTOS="linux"
-GOOS="linux"
-GOPATH="/home/<yourusername>/go"
-GORACE=""
-## more go env's will be listed
-```
-
-##### Build Træfik
-
-Once your environment is set up and the Træfik repository cloned you can build Træfik. You need get `go-bindata` once to be able to use `go generate` command as part of the build.  The steps to build are:
-
-```bash
-cd ~/go/src/github.com/containous/traefik
-
-# Get go-bindata. Please note, the ellipses are required
-go get github.com/jteeuwen/go-bindata/...
-
-# Start build
-
-# generate
-# (required to merge non-code components into the final binary, such as the web dashboard and provider's Go templates)
-go generate
-
-# Standard go build
-go build ./cmd/traefik
-# run other commands like tests
-```
-
-You will find the Træfik executable in the `~/go/src/github.com/containous/traefik` folder as `traefik`.
-
-### Updating the templates
-
-If you happen to update the provider templates (in `/templates`), you need to run `go generate` to update the `autogen` package.
-
-### Setting up dependency management
-
-[dep](https://github.com/golang/dep) is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
-
-If you want to add a dependency, use `dep ensure -add` to have [dep](https://github.com/golang/dep) put it into the vendor folder and update the dep manifest/lock files (`Gopkg.toml` and `Gopkg.lock`, respectively).
-
-A following `make prune-dep` run should be triggered to trim down the size of the vendor folder.
-The final result must be committed into VCS.
-
-Here's a full example using dep to add a new dependency:
-
-```bash
-# install the new main dependency github.com/foo/bar and minimize vendor size
-$ dep ensure -add github.com/foo/bar
-# generate (Only required to integrate other components such as web dashboard)
-$ go generate
-# Standard go build
-$ go build ./cmd/traefik
-# run other commands like tests
-```
-
-### Tests
-
-#### Method 1: `Docker` and `make`
-
-You can run unit tests using the `test-unit` target and the
-integration test using the `test-integration` target.
-
-```bash
-$ make test-unit
-docker build -t "traefik-dev:your-feature-branch" -f build.Dockerfile .
-# […]
-docker run --rm -it -e OS_ARCH_ARG -e OS_PLATFORM_ARG -e TESTFLAGS -v "/home/user/go/src/github/containous/traefik/dist:/go/src/github.com/containous/traefik/dist" "traefik-dev:your-feature-branch" ./script/make.sh generate test-unit
----> Making bundle: generate (in .)
-removed 'gen.go'
-
----> Making bundle: test-unit (in .)
-+ go test -cover -coverprofile=cover.out .
-ok      github.com/containous/traefik   0.005s  coverage: 4.1% of statements
-
-Test success
-```
-
-For development purposes, you can specify which tests to run by using:
-
-```bash
-# Run every tests in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite" make test-integration
-
-# Run the test "MyTest" in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.MyTest" make test-integration
-
-# Run every tests starting with "My", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.My" make test-integration
-
-# Run every tests ending with "Test", in the MyTest suite
-TESTFLAGS="-check.f MyTestSuite.*Test" make test-integration
-```
-
-More: https://labix.org/gocheck
-
-#### Method 2: `go`
-
-Unit tests can be run from the cloned directory by `$ go test ./...` which should return `ok` similar to:
-
-```
-ok      _/home/user/go/src/github/containous/traefik    0.004s
-```
-
-Integration tests must be run from the `integration/` directory and require the `-integration` switch to be passed like this: `$ cd integration && go test -integration ./...`.
-
-## Documentation
-
-The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
-
-### Method 1: `Docker` and `make`
-
-You can test documentation using the `docs` target.
-
-```bash
-$ make docs
-docker build -t traefik-docs -f docs.Dockerfile .
-# […]
-docker run  --rm -v /home/user/go/github/containous/traefik:/mkdocs -p 8000:8000 traefik-docs mkdocs serve
-# […]
-[I 170828 20:47:48 server:283] Serving on http://0.0.0.0:8000
-[I 170828 20:47:48 handlers:60] Start watching changes
-[I 170828 20:47:48 handlers:62] Start detecting changes
-```
-
-And go to [http://127.0.0.1:8000](http://127.0.0.1:8000).
-
-### Method 2: `mkdocs`
-
-First make sure you have python and pip installed
-
-```shell
-$ python --version
-Python 2.7.2
-$ pip --version
-pip 1.5.2
-```
-
-Then install mkdocs with pip
-
-```shell
-pip install --user -r requirements.txt
-```
-
-To test documentation locally run `mkdocs serve` in the root directory, this should start a server locally to preview your changes.
-
-```shell
-$ mkdocs serve
-INFO    -  Building documentation...
-WARNING -  Config value: 'theme'. Warning: The theme 'united' will be removed in an upcoming MkDocs release. See http://www.mkdocs.org/about/release-notes/ for more details

-
-* The status `needs-design-review` is only used in complex/heavy/tricky PRs.
-* From `1` to `2`: 1 design LGTM in comment, by a senior maintainer, if needed.
-* From `2` to `3`: 3 LGTM by any maintainer.
-* If needed, a specific maintainer familiar with a particular domain can be requested for the review.

-## Bots
-
-### [Myrmica Lobicornis](https://github.com/containous/lobicornis/)
-
-**Update and Merge Pull Request**
-
-The maintainer giving the final LGTM must add the `status/3-needs-merge` label to trigger the merge bot.
-
-By default, a squash-rebase merge will be carried out.
-If you want to preserve commits you must add `bot/merge-method-rebase` before `status/3-needs-merge`.
-
-The status `status/4-merge-in-progress` is only for the bot.
-
-If the bot is not able to perform the merge, the label `bot/need-human-merge` is added.  
-In this case you must solve conflicts/CI/... and after you only need to remove `bot/need-human-merge`.
-
-A maintainer can add `bot/no-merge` on a PR if he want (temporarily) prevent a merge by the bot.
-
-`bot/light-review` can be used to decrease required LGTM from 3 to 1 when:
-
-- vendor updates from previously reviewed PRs
-- merges branches into master
-- prepare release

+Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.

 ## Overview
 
-Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
+Imagine that you have deployed a bunch of microservices with the help of an orchestrator (like Swarm or Kubernetes) or a service registry (like etcd or consul).
+Now you want users to access these microservices, and you need a reverse proxy.
 
-- domain `api.domain.com` will point the microservice `api` in your private network
-- path `domain.com/web` will point the microservice `web` in your private network
-- domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
+Traditional reverse-proxies require that you configure _each_ route that will connect paths and subdomains to _each_ microservice. 
+In an environment where you add, remove, kill, upgrade, or scale your services _many_ times a day, the task of keeping the routes up to date becomes tedious. 
 
-Microservices are often deployed in dynamic environments where services are added, removed, killed, upgraded or scaled many times a day.
+**This is when Traefik can help you!**
 
-Traditional reverse-proxies are not natively dynamic. You can't change their configuration and hot-reload easily.
+Traefik listens to your service registry/orchestrator API and instantly generates the routes so your microservices are connected to the outside world -- without further intervention from your part. 
 
-Here enters Træfik.
-
-![Architecture](docs/img/architecture.png)
-
-Træfik can listen to your service registry/orchestrator API, and knows each time a microservice is added, removed, killed or upgraded, and can generate its configuration automatically.
-Routes to your services will be created instantly.
-
-Run it and forget it!
+**Run Traefik and let it do the work for you!** 
+_(But if you'd rather configure some of your routes manually, Traefik supports that too!)_

-## Release cycle
-
-- Release: We try to release a new version every 2 months
-  - i.e.: 1.3.0, 1.4.0, 1.5.0
-- Release candidate: we do RC (1.**x**.0-rc**y**) before the final release (1.**x**.0)
-  - i.e.: 1.1.0-rc1 -> 1.1.0-rc2 -> 1.1.0-rc3 -> 1.1.0-rc4 -> 1.1.0
-- Bug-fixes: For each version we release bug fixes
-  - i.e.: 1.1.1, 1.1.2, 1.1.3
-  - those versions contain only bug-fixes
-  - no additional features are delivered in those versions
-- Each version is supported until the next one is released
-  - i.e.: 1.1.x will be supported until 1.2.0 is out
-- We use [Semantic Versioning](http://semver.org/)

-# Basics
-
-## Concepts
-
-Let's take our example from the [overview](/#overview) again:
-
-
-> Imagine that you have deployed a bunch of microservices on your infrastructure. You probably used a service registry (like etcd or consul) and/or an orchestrator (swarm, Mesos/Marathon) to manage all these services.
-> If you want your users to access some of your microservices from the Internet, you will have to use a reverse proxy and configure it using virtual hosts or prefix paths:
-
-> - domain `api.domain.com` will point the microservice `api` in your private network
-> - path `domain.com/web` will point the microservice `web` in your private network
-> - domain `backoffice.domain.com` will point the microservices `backoffice` in your private network, load-balancing between your multiple instances
-
-> ![Architecture](img/architecture.png)
-
-Let's zoom on Træfik and have an overview of its internal architecture:
-
-
-![Architecture](img/internal.png)
-
-- Incoming requests end on [entrypoints](#entrypoints), as the name suggests, they are the network entry points into Træfik (listening port, SSL, traffic redirection...).
-- Traffic is then forwarded to a matching [frontend](#frontends). A frontend defines routes from [entrypoints](#entrypoints) to [backends](#backends).
-Routes are created using requests fields (`Host`, `Path`, `Headers`...) and can match or not a request.
-- The [frontend](#frontends) will then send the request to a [backend](#backends). A backend can be composed by one or more [servers](#servers), and by a load-balancing strategy.
-- Finally, the [server](#servers) will forward the request to the corresponding microservice in the private network.
-
-### Entrypoints
-
-Entrypoints are the network entry points into Træfik.
-They can be defined using:
-
-- a port (80, 443...)
-- SSL (Certificates, Keys, authentication with a client certificate signed by a trusted CA...)
-- redirection to another entrypoint (redirect `HTTP` to `HTTPS`)
-
-Here is an example of entrypoints definition:
-
-```toml
-[entryPoints]
-  [entryPoints.http]
-  address = ":80"
-    [entryPoints.http.redirect]
-    entryPoint = "https"
-  [entryPoints.https]
-  address = ":443"
-    [entryPoints.https.tls]
-      [[entryPoints.https.tls.certificates]]
-      certFile = "tests/traefik.crt"
-      keyFile = "tests/traefik.key"
-```
-
-- Two entrypoints are defined `http` and `https`.
-- `http` listens on port `80` and `https` on port `443`.
-- We enable SSL on `https` by giving a certificate and a key.
-- We also redirect all the traffic from entrypoint `http` to `https`.
-
-And here is another example with client certificate authentication:
-
-```toml
-[entryPoints]
-  [entryPoints.https]
-  address = ":443"
-  [entryPoints.https.tls]
-    [entryPoints.https.tls]
-      [entryPoints.https.tls.ClientCA]
-      files = ["tests/clientca1.crt", "tests/clientca2.crt"]
-      optional = false
-      [[entryPoints.https.tls.certificates]]
-      certFile = "tests/traefik.crt"
-      keyFile = "tests/traefik.key"
-```
-
-- We enable SSL on `https` by giving a certificate and a key.
-- One or several files containing Certificate Authorities in PEM format are added.
-- It is possible to have multiple CA:s in the same file or keep them in separate files.
-
-### Frontends
-
-A frontend consists of a set of rules that determine how incoming requests are forwarded from an entrypoint to a backend.
-
-Rules may be classified in one of two groups: Modifiers and matchers.
-
-#### Modifiers
-
-Modifier rules only modify the request. They do not have any impact on routing decisions being made.
-
-Following is the list of existing modifier rules:
-
-- `AddPrefix: /products`: Add path prefix to the existing request path prior to forwarding the request to the backend.
-- `ReplacePath: /serverless-path`: Replaces the path and adds the old path to the `X-Replaced-Path` header. Useful for mapping to AWS Lambda or Google Cloud Functions.
-- `ReplacePathRegex: ^/api/v2/(.*) /api/$1`: Replaces the path with a regular expression and adds the old path to the `X-Replaced-Path` header. Separate the regular expression and the replacement by a space.
-
-#### Matchers
-
-Matcher rules determine if a particular request should be forwarded to a backend.
-
-Separate multiple rule values by `,` (comma) in order to enable ANY semantics (i.e., forward a request if any rule matches).
-Does not work for `Headers` and `HeadersRegexp`.
-
-Separate multiple rule values by `;` (semicolon) in order to enable ALL semantics (i.e., forward a request if all rules match).
-
-Following is the list of existing matcher rules along with examples:
-
-| Matcher                                                    | Description                                                                                                                                                                                                                                                                             |
-|------------------------------------------------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
-| `Headers: Content-Type, application/json`                  | Match HTTP header. It accepts a comma-separated key/value pair where both key and value must be literals.                                                                                                                                                                               |
-| `HeadersRegexp: Content-Type, application/(text/json)`     | Match HTTP header. It accepts a comma-separated key/value pair where the key must be a literal and the value may be a literal or a regular expression.                                                                                                                                  |
-| `Host: traefik.io, www.traefik.io`                         | Match request host. It accepts a sequence of literal hosts.                                                                                                                                                                                                                             |
-| `HostRegexp: traefik.io, {subdomain:[a-z]+}.traefik.io`    | Match request host. It accepts a sequence of literal and regular expression hosts.                                                                                                                                                                                                      |
-| `Method: GET, POST, PUT`                                   | Match request HTTP method. It accepts a sequence of HTTP methods.                                                                                                                                                                                                                       |
-| `Path: /products/, /articles/{category}/{id:[0-9]+}`       | Match exact request path. It accepts a sequence of literal and regular expression paths.                                                                                                                                                                                                |
-| `PathStrip: /products/`                                    | Match exact path and strip off the path prior to forwarding the request to the backend. It accepts a sequence of literal paths.                                                                                                                                                         |
-| `PathStripRegex: /articles/{category}/{id:[0-9]+}`         | Match exact path and strip off the path prior to forwarding the request to the backend. It accepts a sequence of literal and regular expression paths.                                                                                                                                  |
-| `PathPrefix: /products/, /articles/{category}/{id:[0-9]+}` | Match request prefix path. It accepts a sequence of literal and regular expression prefix paths.                                                                                                                                                                                        |
-| `PathPrefixStrip: /products/`                              | Match request prefix path and strip off the path prefix prior to forwarding the request to the backend. It accepts a sequence of literal prefix paths. Starting with Traefik 1.3, the stripped prefix path will be available in the `X-Forwarded-Prefix` header.                        |
-| `PathPrefixStripRegex: /articles/{category}/{id:[0-9]+}`   | Match request prefix path and strip off the path prefix prior to forwarding the request to the backend. It accepts a sequence of literal and regular expression prefix paths. Starting with Traefik 1.3, the stripped prefix path will be available in the `X-Forwarded-Prefix` header. |
-| `Query: foo=bar, bar=baz`                                  | Match Query String parameters. It accepts a sequence of key=value pairs.                                                                                                                                                                                                                |
-
-In order to use regular expressions with Host and Path matchers, you must declare an arbitrarily named variable followed by the colon-separated regular expression, all enclosed in curly braces. Any pattern supported by [Go's regexp package](https://golang.org/pkg/regexp/) may be used (example: `/posts/{id:[0-9]+}`).
-
-!!! note
-    The variable has no special meaning; however, it is required by the [gorilla/mux](https://github.com/gorilla/mux) dependency which embeds the regular expression and defines the syntax.
-
-You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
-You can also optionally enable `passTLSCert` to forward TLS Client certificates to the backend.
-
-##### Path Matcher Usage Guidelines
-
-This section explains when to use the various path matchers.
-
-Use `Path` if your backend listens on the exact path only. For instance, `Path: /products` would match `/products` but not `/products/shoes`.
-
-Use a `*Prefix*` matcher if your backend listens on a particular base path but also serves requests on sub-paths.
-For instance, `PathPrefix: /products` would match `/products` but also `/products/shoes` and `/products/shirts`.
-Since the path is forwarded as-is, your backend is expected to listen on `/products`.
-
-Use a `*Strip` matcher if your backend listens on the root path (`/`) but should be routeable on a specific prefix.
-For instance, `PathPrefixStrip: /products` would match `/products` but also `/products/shoes` and `/products/shirts`.  
-Since the path is stripped prior to forwarding, your backend is expected to listen on `/`.  
-If your backend is serving assets (e.g., images or Javascript files), chances are it must return properly constructed relative URLs.  
-Continuing on the example, the backend should return `/products/shoes/image.png` (and not `/images.png` which Traefik would likely not be able to associate with the same backend).  
-The `X-Forwarded-Prefix` header (available since Traefik 1.3) can be queried to build such URLs dynamically.
-
-Instead of distinguishing your backends by path only, you can add a Host matcher to the mix.
-That way, namespacing of your backends happens on the basis of hosts in addition to paths.
-
-#### Examples
-
-Here is an example of frontends definition:
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend2"
-    [frontends.frontend1.routes.test_1]
-    rule = "Host:test.localhost,test2.localhost"
-  [frontends.frontend2]
-  backend = "backend1"
-  passHostHeader = true
-  passTLSCert = true
-  priority = 10
-  entrypoints = ["https"] # overrides defaultEntryPoints
-    [frontends.frontend2.routes.test_1]
-    rule = "HostRegexp:localhost,{subdomain:[a-z]+}.localhost"
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Host:test3.localhost;Path:/test"
-```
-
-- Three frontends are defined: `frontend1`, `frontend2` and `frontend3`
-- `frontend1` will forward the traffic to the `backend2` if the rule `Host:test.localhost,test2.localhost` is matched
-- `frontend2` will forward the traffic to the `backend1` if the rule `Host:localhost,{subdomain:[a-z]+}.localhost` is matched (forwarding client `Host` header to the backend)
-- `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched
-
-#### Combining multiple rules
-
-As seen in the previous example, you can combine multiple rules.
-In TOML file, you can use multiple routes:
-
-```toml
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Host:test3.localhost"
-    [frontends.frontend3.routes.test_2]
-    rule = "Path:/test"
-```
-
-Here `frontend3` will forward the traffic to the `backend2` if the rules `Host:test3.localhost` **AND** `Path:/test` are matched.
-
-You can also use the notation using a `;` separator, same result:
-
-```toml
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Host:test3.localhost;Path:/test"
-```
-
-Finally, you can create a rule to bind multiple domains or Path to a frontend, using the `,` separator:
-
-```toml
- [frontends.frontend2]
-    [frontends.frontend2.routes.test_1]
-    rule = "Host:test1.localhost,test2.localhost"
-  [frontends.frontend3]
-  backend = "backend2"
-    [frontends.frontend3.routes.test_1]
-    rule = "Path:/test1,/test2"
-```
-
-#### Rules Order
-
-When combining `Modifier` rules with `Matcher` rules, it is important to remember that `Modifier` rules **ALWAYS** apply after the `Matcher` rules.
-
-The following rules are both `Matchers` and `Modifiers`, so the `Matcher` portion of the rule will apply first, and the `Modifier` will apply later.
-
-- `PathStrip`
-- `PathStripRegex`
-- `PathPrefixStrip`
-- `PathPrefixStripRegex`
-
-`Modifiers` will be applied in a pre-determined order regardless of their order in the `rule` configuration section.
-
-1. `PathStrip`
-2. `PathPrefixStrip`
-3. `PathStripRegex`
-4. `PathPrefixStripRegex`
-5. `AddPrefix`
-6. `ReplacePath`
-
-#### Priorities
-
-By default, routes will be sorted (in descending order) using rules length (to avoid path overlap):
-`PathPrefix:/12345` will be matched before `PathPrefix:/1234` that will be matched before `PathPrefix:/1`.
-
-You can customize priority by frontend:
-
-```toml
-  [frontends]
-    [frontends.frontend1]
-    backend = "backend1"
-    priority = 10
-    passHostHeader = true
-      [frontends.frontend1.routes.test_1]
-      rule = "PathPrefix:/to"
-    [frontends.frontend2]
-    priority = 5
-    backend = "backend2"
-    passHostHeader = true
-      [frontends.frontend2.routes.test_1]
-      rule = "PathPrefix:/toto"
-```
-
-Here, `frontend1` will be matched before `frontend2` (`10 > 5`).
-
-#### Custom headers
-
-Custom headers can be configured through the frontends, to add headers to either requests or responses that match the frontend's rules.
-This allows for setting headers such as `X-Script-Name` to be added to the request, or custom headers to be added to the response.
-
-!!! warning
-    If the custom header name is the same as one header name of the request or response, it will be replaced.
-
-In this example, all matches to the path `/cheese` will have the `X-Script-Name` header added to the proxied request, and the `X-Custom-Response-Header` added to the response.
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend1"
-    [frontends.frontend1.headers.customresponseheaders]
-    X-Custom-Response-Header = "True"
-    [frontends.frontend1.headers.customrequestheaders]
-    X-Script-Name = "test"
-    [frontends.frontend1.routes.test_1]
-    rule = "PathPrefixStrip:/cheese"
-```
-
-In this second  example, all matches to the path `/cheese` will have the `X-Script-Name` header added to the proxied request, the `X-Custom-Request-Header` removed to the request and the `X-Custom-Response-Header` removed to the response.
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend1"
-    [frontends.frontend1.headers.customresponseheaders]
-    X-Custom-Response-Header = ""
-    [frontends.frontend1.headers.customrequestheaders]
-    X-Script-Name = "test"
-    X-Custom-Request-Header = ""
-    [frontends.frontend1.routes.test_1]
-    rule = "PathPrefixStrip:/cheese"
-```
-
-#### Security headers
-
-Security related headers (HSTS headers, SSL redirection, Browser XSS filter, etc) can be added and configured per frontend in a similar manner to the custom headers above.
-This functionality allows for some easy security features to quickly be set.
-
-An example of some of the security headers:
-
-```toml
-[frontends]
-  [frontends.frontend1]
-  backend = "backend1"
-    [frontends.frontend1.headers]
-    FrameDeny = true
-    [frontends.frontend1.routes.test_1]
-    rule = "PathPrefixStrip:/cheddar"
-  [frontends.frontend2]
-  backend = "backend2"
-    [frontends.frontend2.headers]
-    SSLRedirect = true
-    [frontends.frontend2.routes.test_1]
-    rule = "PathPrefixStrip:/stilton"
-```
-
-In this example, traffic routed through the first frontend will have the `X-Frame-Options` header set to `DENY`, and the second will only allow HTTPS request through, otherwise will return a 301 HTTPS redirect.
-
-!!! note
-    The detailed documentation for those security headers can be found in [unrolled/secure](https://github.com/unrolled/secure#available-options).
-
-### Backends
-
-A backend is responsible to load-balance the traffic coming from one or more frontends to a set of http servers.
-
-Various methods of load-balancing are supported:
-
-- `wrr`: Weighted Round Robin.
-- `drr`: Dynamic Round Robin: increases weights on servers that perform better than others.
-    It also rolls back to original weights if the servers have changed.
-
-A circuit breaker can also be applied to a backend, preventing high loads on failing servers.
-Initial state is Standby. CB observes the statistics and does not modify the request.
-In case the condition matches, CB enters Tripped state, where it responds with predefined code or redirects to another frontend.
-Once Tripped timer expires, CB enters Recovering state and resets all stats.
-In case the condition does not match and recovery timer expires, CB enters Standby state.
-
-It can be configured using:
-
-- Methods: `LatencyAtQuantileMS`, `NetworkErrorRatio`, `ResponseCodeRatio`
-- Operators:  `AND`, `OR`, `EQ`, `NEQ`, `LT`, `LE`, `GT`, `GE`
-
-For example:
-
-- `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window for a frontend.
-- `LatencyAtQuantileMS(50.0) > 50`:  watch latency at quantile in milliseconds.
-- `ResponseCodeRatio(500, 600, 0, 600) > 0.5`: ratio of response codes in ranges [500-600) and [0-600).
-
-To proactively prevent backends from being overwhelmed with high load, a maximum connection limit can also be applied to each backend.
-
-Maximum connections can be configured by specifying an integer value for `maxconn.amount` and `maxconn.extractorfunc` which is a strategy used to determine how to categorize requests in order to evaluate the maximum connections.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.maxconn]
-       amount = 10
-       extractorfunc = "request.host"
-```
-
-- `backend1` will return `HTTP code 429 Too Many Requests` if there are already 10 requests in progress for the same Host header.
-- Another possible value for `extractorfunc` is `client.ip` which will categorize requests based on client source ip.
-- Lastly `extractorfunc` can take the value of `request.header.ANY_HEADER` which will categorize requests based on `ANY_HEADER` that you provide.
-
-### Sticky sessions
-
-Sticky sessions are supported with both load balancers.  
-When sticky sessions are enabled, a cookie is set on the initial request.
-The default cookie name is an abbreviation of a sha1 (ex: `_1d52e`).
-On subsequent requests, the client will be directed to the backend stored in the cookie if it is still healthy.
-If not, a new backend will be assigned.
-
-
-```toml
-[backends]
-  [backends.backend1]
-    # Enable sticky session
-    [backends.backend1.loadbalancer.stickiness]
-
-    # Customize the cookie name
-    #
-    # Optional
-    # Default: a sha1 (6 chars)
-    #
-    #  cookieName = "my_cookie"
-```
-
-The deprecated way:
-
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.loadbalancer]
-      sticky = true
-```
-
-### Health Check
-
-A health check can be configured in order to remove a backend from LB rotation as long as it keeps returning HTTP status codes other than `200 OK` to HTTP GET requests periodically carried out by Traefik.  
-The check is defined by a pathappended to the backend URL and an interval (given in a format understood by [time.ParseDuration](https://golang.org/pkg/time/#ParseDuration)) specifying how often the health check should be executed (the default being 30 seconds).
-Each backend must respond to the health check within 5 seconds.  
-By default, the port of the backend server is used, however, this may be overridden.
-
-A recovering backend returning 200 OK responses again is being returned to the
-LB rotation pool.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.healthcheck]
-    path = "/health"
-    interval = "10s"
-```
-
-To use a different port for the healthcheck:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.healthcheck]
-    path = "/health"
-    interval = "10s"
-    port = 8080
-```
-
-### Servers
-
-Servers are simply defined using a `url`. You can also apply a custom `weight` to each server (this will be used by load-balancing).
-
-!!! note
-    Paths in `url` are ignored. Use `Modifier` to specify paths instead.
-
-Here is an example of backends and servers definition:
-
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.circuitbreaker]
-    expression = "NetworkErrorRatio() > 0.5"
-    [backends.backend1.servers.server1]
-    url = "http://172.17.0.2:80"
-    weight = 10
-    [backends.backend1.servers.server2]
-    url = "http://172.17.0.3:80"
-    weight = 1
-  [backends.backend2]
-    [backends.backend2.LoadBalancer]
-    method = "drr"
-    [backends.backend2.servers.server1]
-    url = "http://172.17.0.4:80"
-    weight = 1
-    [backends.backend2.servers.server2]
-    url = "http://172.17.0.5:80"
-    weight = 2
-```
-
-- Two backends are defined: `backend1` and `backend2`
-- `backend1` will forward the traffic to two servers: `http://172.17.0.2:80"` with weight `10` and `http://172.17.0.3:80` with weight `1` using default `wrr` load-balancing strategy.
-- `backend2` will forward the traffic to two servers: `http://172.17.0.4:80"` with weight `1` and `http://172.17.0.5:80` with weight `2` using `drr` load-balancing strategy.
-- a circuit breaker is added on `backend1` using the expression `NetworkErrorRatio() > 0.5`: watch error ratio over 10 second sliding window
-
-
-## Configuration
-
-Træfik's configuration has two parts:
-
-- The [static Træfik configuration](/basics#static-trfik-configuration) which is loaded only at the beginning.
-- The [dynamic Træfik configuration](/basics#dynamic-trfik-configuration) which can be hot-reloaded (no need to restart the process).
-
-### Static Træfik configuration
-
-The static configuration is the global configuration which is setting up connections to configuration backends and entrypoints.
-
-Træfik can be configured using many configuration sources with the following precedence order.
-Each item takes precedence over the item below it:
-
-- [Key-value store](/basics/#key-value-stores)
-- [Arguments](/basics/#arguments)
-- [Configuration file](/basics/#configuration-file)
-- Default
-
-It means that arguments override configuration file, and key-value store overrides arguments.
-
-!!! note 
-    the provider-enabling argument parameters (e.g., `--docker`) set all default values for the specific provider.  
-    It must not be used if a configuration source with less precedence wants to set a non-default provider value.
-
-#### Configuration file
-
-By default, Træfik will try to find a `traefik.toml` in the following places:
-
-- `/etc/traefik/`
-- `$HOME/.traefik/`
-- `.` _the working directory_
-
-You can override this by setting a `configFile` argument:
-
-```bash
-traefik --configFile=foo/bar/myconfigfile.toml
-```
-
-Please refer to the [global configuration](/configuration/commons) section to get documentation on it.
-
-#### Arguments
-
-Each argument (and command) is described in the help section:
-
-```bash
-traefik --help
-```
-
-Note that all default values will be displayed as well.
-
-#### Key-value stores
-
-Træfik supports several Key-value stores:
-
-- [Consul](https://consul.io)
-- [etcd](https://coreos.com/etcd/)
-- [ZooKeeper](https://zookeeper.apache.org/)
-- [boltdb](https://github.com/boltdb/bolt)
-
-Please refer to the [User Guide Key-value store configuration](/user-guide/kv-config/) section to get documentation on it.
-
-### Dynamic Træfik configuration
-
-The dynamic configuration concerns :
-
-- [Frontends](/basics/#frontends)
-- [Backends](/basics/#backends)
-- [Servers](/basics/#servers)
-- HTTPS Certificates
-
-Træfik can hot-reload those rules which could be provided by [multiple configuration backends](/configuration/commons).
-
-We only need to enable `watch` option to make Træfik watch configuration backend changes and generate its configuration automatically.
-Routes to services will be created and updated instantly at any changes.
-
-Please refer to the [configuration backends](/configuration/commons) section to get documentation on it.
-
-## Commands
-
-### traefik
-
-Usage:
-```bash
-traefik [command] [--flag=flag_argument]
-```
-
-List of Træfik available commands with description :
-
-- `version` : Print version
-- `storeconfig` : Store the static Traefik configuration into a Key-value stores. Please refer to the [Store Træfik configuration](/user-guide/kv-config/#store-configuration-in-key-value-store) section to get documentation on it.
-- `bug`: The easiest way to submit a pre-filled issue.
-- `healthcheck`: Calls Traefik `/ping` to check health.
-
-Each command may have related flags.
-
-All those related flags will be displayed with :
-
-```bash
-traefik [command] --help
-```
-
-Each command is described at the beginning of the help section:
-
-```bash
-traefik --help
-```
-
-### Command: bug
-
-Here is the easiest way to submit a pre-filled issue on [Træfik GitHub](https://github.com/containous/traefik).
-
-```bash
-traefik bug
-```
-
-Watch [this demo](https://www.youtube.com/watch?v=Lyz62L8m93I).
-
-### Command: healthcheck
-
-This command allows to check the health of Traefik. Its exit status is `0` if Traefik is healthy and `1` if it is unhealthy.
-
-This can be used with Docker [HEALTHCHECK](https://docs.docker.com/engine/reference/builder/#healthcheck) instruction or any other health check orchestration mechanism.
-
-!!! note
-    The [`ping`](/configuration/ping) must be enabled to allow the `healthcheck` command to call `/ping`.
-
-```bash
-traefik healthcheck
-```
-```bash
-OK: http://:8082/ping
-```
-
-
-## Collected Data
-
-**This feature is disabled by default.**
-
-You can read the public proposal on this topic [here](https://github.com/containous/traefik/issues/2369).
-
-### Why ?
-
-In order to help us learn more about how Træfik is being used and improve it, we collect anonymous usage statistics from running instances.
-Those data help us prioritize our developments and focus on what's more important (for example, which configuration backend is used and which is not used).
-
-### What ?
-
-Once a day (the first call begins 10 minutes after the start of Træfik), we collect:
-
-- the Træfik version
-- a hash of the configuration
-- an **anonymous version** of the static configuration:
-    - token, user name, password, URL, IP, domain, email, etc, are removed
-
-!!! note
-    We do not collect the dynamic configuration (frontends & backends).
-
-!!! note
-    We do not collect data behind the scenes to run advertising programs or to sell such data to third-party.
-
-#### Here is an example
-
-- Source configuration:
-
-```toml
-[entryPoints]
-    [entryPoints.http]
-       address = ":80"
-
-[api]
-
-[Docker]
-  endpoint = "tcp://10.10.10.10:2375"
-  domain = "foo.bir"
-  exposedByDefault = true
-  swarmMode = true
-
-  [Docker.TLS]
-    CA = "dockerCA"
-    Cert = "dockerCert"
-    Key = "dockerKey"
-    InsecureSkipVerify = true
-
-[ECS]
-  Domain = "foo.bar"
-  ExposedByDefault = true
-  Clusters = ["foo-bar"]
-  Region = "us-west-2"
-  AccessKeyID = "AccessKeyID"
-  SecretAccessKey = "SecretAccessKey"
-```
-
-- Obfuscated and anonymous configuration:
-
-```toml
-[entryPoints]
-    [entryPoints.http]
-       address = ":80"
-
-[api]
-
-[Docker]
-  Endpoint = "xxxx"
-  Domain = "xxxx"
-  ExposedByDefault = true
-  SwarmMode = true
-
-  [Docker.TLS]
-    CA = "xxxx"
-    Cert = "xxxx"
-    Key = "xxxx"
-    InsecureSkipVerify = false
-
-[ECS]
-  Domain = "xxxx"
-  ExposedByDefault = true
-  Clusters = []
-  Region = "us-west-2"
-  AccessKeyID = "xxxx"
-  SecretAccessKey = "xxxx"
-```
-
-### Show me the code !
-
-If you want to dig into more details, here is the source code of the collecting system: [collector.go](https://github.com/containous/traefik/blob/master/collector/collector.go)
-
-By default we anonymize all configuration fields, except fields tagged with `export=true`.
-
-You can check all fields in the [godoc](https://godoc.org/github.com/containous/traefik/configuration#GlobalConfiguration).
-
-### How to enable this ?
-
-You can enable the collecting system by:
-
-- adding this line in the configuration TOML file:
-
-```toml
-# Send anonymous usage data
-#
-# Optional
-# Default: false
-#
-sendAnonymousUsage = true
-```
-
-- adding this flag in the CLI:
-
-```bash
-./traefik --sendAnonymousUsage=true
-```

-# Benchmarks
-
-## Configuration
-
-I would like to thanks [vincentbernat](https://github.com/vincentbernat) from [exoscale.ch](https://www.exoscale.ch) who kindly provided the infrastructure needed for the benchmarks.
-
-I used 4 VMs for the tests with the following configuration:
-
-- 32 GB RAM
-- 8 CPU Cores
-- 10 GB SSD
-- Ubuntu 14.04 LTS 64-bit
-
-## Setup
-
-1. One VM used to launch the benchmarking tool [wrk](https://github.com/wg/wrk)
-2. One VM for Traefik (v1.0.0-beta.416) / nginx (v1.4.6)
-3. Two VMs for 2 backend servers in go [whoami](https://github.com/emilevauge/whoamI/)
-
-Each VM has been tuned using the following limits:
-
-```bash
-sysctl -w fs.file-max="9999999"

-
-## Conclusion
-
-Traefik is obviously slower than Nginx, but not so much: Traefik can serve 28392 requests/sec and Nginx 33591 requests/sec which gives a ratio of 85%.
-Not bad for young project :) !
-
-Some areas of possible improvements:
-
-- Use [GO_REUSEPORT](https://github.com/kavu/go_reuseport) listener
-- Run a separate server instance per CPU core with `GOMAXPROCS=1` (it appears during benchmarks that there is a lot more context switches with Traefik than with nginx)

-!!! note
-    Even if `TLS-SNI-01` challenge is [disabled](https://community.letsencrypt.org/t/2018-01-11-update-regarding-acme-tls-sni-and-shared-hosting-infrastructure/50188) for the moment, it stays the _by default_ ACME Challenge in Træfik.
-    If `TLS-SNI-01` challenge is not re-enabled in the future, it we will be removed from Træfik.
-
-!!! note
-    If `TLS-SNI-01` challenge is used, `acme.entryPoint` has to be reachable by Let's Encrypt through the port 443.
-    If `HTTP-01` challenge is used, `acme.httpChallenge.entryPoint` has to be defined and reachable by Let's Encrypt through the port 80.
-    These are Let's Encrypt limitations as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
-
-### `storage`
-
-```toml
-[acme]
-# ...
-storage = "acme.json"
-# ...
-```
-
-File or key used for certificates storage.
-
-**WARNING:** If you use Træfik in Docker, you have 2 options:
-
-- create a file on your host and mount it as a volume:
-```toml
-storage = "acme.json"
-```
-```bash
-docker run -v "/my/host/acme.json:acme.json" traefik
-```
-
-- mount the folder containing the file as a volume
-```toml
-storage = "/etc/traefik/acme/acme.json"
-```
-```bash
-docker run -v "/my/host/acme:/etc/traefik/acme" traefik
-```
-
-!!! note
-    `storage` replaces `storageFile` which is deprecated.
-
-!!! note
-    During Træfik configuration migration from a configuration file to a KV store (thanks to `storeconfig` subcommand as described [here](/user-guide/kv-config/#store-configuration-in-key-value-store)), if ACME certificates have to be migrated too, use both `storageFile` and `storage`.
-
-    - `storageFile` will contain the path to the `acme.json` file to migrate.
-    - `storage` will contain the key where the certificates will be stored.
-
-### `acme.httpChallenge`
-
-Use `HTTP-01` challenge to generate/renew ACME certificates.
-
-The redirection is fully compatible with the HTTP-01 challenge.
-You can use redirection with HTTP-01 challenge without problem.
-
-```toml
-[acme]
-# ...
-entryPoint = "https"
-[acme.httpChallenge]
-  entryPoint = "http"
-```
-
-#### `entryPoint`
-
-Specify the entryPoint to use during the challenges.
-
-```toml
-[entryPoints]
-  [entryPoints.http]
-  address = ":80"
-  [entryPoints.https]
-  address = ":443"
-    [entryPoints.https.tls]
-# ...
-
-[acme]
-  # ...
-  entryPoint = "https"
-  [acme.httpChallenge]
-    entryPoint = "http"
-```
-
-!!! note
-    `acme.httpChallenge.entryPoint` has to be reachable by Let's Encrypt through the port 80.
-    It's a Let's Encrypt limitation as described on the [community forum](https://community.letsencrypt.org/t/support-for-ports-other-than-80-and-443/3419/72).
-
-### `acme.dnsChallenge`
-
-Use `DNS-01` challenge to generate/renew ACME certificates.
-
-```toml
-[acme]
-# ...
-[acme.dnsChallenge]
-  provider = "digitalocean"
-  delayBeforeCheck = 0
-# ...
-```
-
-#### `provider` 
-

-#### `delayBeforeCheck`
-
-By default, the `provider` will verify the TXT DNS challenge record before letting ACME verify.  
-If `delayBeforeCheck` is greater than zero, avoid this & instead just wait so many seconds.
-
-Useful if internal networks block external DNS queries.
-
-!!! note
-    This field has no sense if a `provider` is not defined.
-
-### `onDemand` (Deprecated)
-
-!!! warning
-    This option is deprecated.
-
-```toml
-[acme]
-# ...
-onDemand = true
-# ...
-```
-
-Enable on demand certificate.
-
-This will request a certificate from Let's Encrypt during the first TLS handshake for a hostname that does not yet have a certificate.
-
-!!! warning
-    TLS handshakes will be slow when requesting a hostname certificate for the first time, this can lead to DoS attacks.
-    
-!!! warning
-    Take note that Let's Encrypt have [rate limiting](https://letsencrypt.org/docs/rate-limits).
-
-### `onHostRule`
-
-```toml
-[acme]
-# ...
-onHostRule = true
-# ...
-```
-
-Enable certificate generation on frontends Host rules.
-
-This will request a certificate from Let's Encrypt for each frontend with a Host rule.
-
-For example, a rule `Host:test1.traefik.io,test2.traefik.io` will request a certificate with main domain `test1.traefik.io` and SAN `test2.traefik.io`.
-
-### `caServer`
-
-```toml
-[acme]
-# ...
-caServer = "https://acme-staging.api.letsencrypt.org/directory"
-# ...
-```
-
-CA server to use.
-
-- Uncomment the line to run on the staging Let's Encrypt server.
-- Leave comment to go to prod.
-
-### `acme.domains`
-
-```toml
-[acme]
-# ...
-[[acme.domains]]
-  main = "local1.com"
-  sans = ["test1.local1.com", "test2.local1.com"]
-[[acme.domains]]
-  main = "local2.com"
-  sans = ["test1.local2.com", "test2.local2.com"]
-[[acme.domains]]
-  main = "local3.com"
-[[acme.domains]]
-  main = "local4.com"
-# ...
-```
-
-You can provide SANs (alternative domains) to each main domain.
-All domains must have A/AAAA records pointing to Træfik.
-
-!!! warning
-    Take note that Let's Encrypt have [rate limiting](https://letsencrypt.org/docs/rate-limits).
-
-Each domain & SANs will lead to a certificate request.
-
-### `dnsProvider` (Deprecated)
-
-!!! warning
-    This option is deprecated.
-    Please refer to [DNS challenge provider section](/configuration/acme/#provider)
-
-### `delayDontCheckDNS` (Deprecated)

-### Examples
-
-If you want that Træfik uses Consul tags correctly you need to defined them like that:
-```json
-traefik.enable=true
-traefik.tags=api
-traefik.tags=external
-```
-
-If the prefix defined in Træfik configuration is `bla`, tags need to be defined like that:
-```json
-bla.enable=true
-bla.tags=api
-bla.tags=external
-```

-## Labels: overriding default behaviour
-
-!!! note
-    If you use a compose file, labels should be defined in the `deploy` part of your service.
-
-    This behavior is only enabled for docker-compose version 3+ ([Compose file reference](https://docs.docker.com/compose/compose-file/#labels-1)).
-
-```yaml
-version: "3"
-services:
-  whoami:
-    deploy:
-      labels:
-        traefik.docker.network: traefik
-```
-
-### On Containers
-
-Labels can be used on containers to override default behaviour.

-
-!!! note
-    If a label is defined both as a `container label` and a `service label` (for example `traefik.<service-name>.port=PORT` and `traefik.port=PORT` ), the `service label` is used to defined the `<service-name>` property (`port` in the example).
-
-    It's possible to mix `container labels` and `service labels`, in this case `container labels` are used as default value for missing `service labels` but no frontends are going to be created with the `container labels`.
-
-    More details in this [example](/user-guide/docker-and-lets-encrypt/#labels).
-
-!!! warning
-    When running inside a container, Træfik will need network access through:
-
-    `docker network connect <network> <traefik-container>`

-
-## Table Items
-
-Items in the `dynamodb` table must have three attributes:
-
-- `id` (string): The id is the primary key.
-- `name`(string): The name is used as the name of the frontend or backend.
-- `frontend` or `backend` (map): This attribute's structure matches exactly the structure of a Frontend or Backend type in Traefik.  
-    See `types/types.go` for details.  
-    The presence or absence of this attribute determines its type.
-    So an item should never have both a `frontend` and a `backend` attribute.

-## Configuration mode
-
-You have three choices:
-
-- [Simple](/configuration/backends/file/#simple)
-- [Rules in a Separate File](/configuration/backends/file/#rules-in-a-separate-file)
-- [Multiple `.toml` Files](/configuration/backends/file/#multiple-toml-files)
-
-To enable the file backend, you must either pass the `--file` option to the Træfik binary or put the `[file]` section (with or without inner settings) in the configuration file.
-
-The configuration file allows managing both backends/frontends and HTTPS certificates (which are not [Let's Encrypt](https://letsencrypt.org) certificates generated through Træfik).
-
-### Simple
-
-Add your configuration at the end of the global configuration file `traefik.toml`:
-
-```toml
-defaultEntryPoints = ["http", "https"]
-
-[entryPoints]
-  [entryPoints.http]
-    # ...
-  [entryPoints.https]
-    # ...
-
-[file]
-
-# rules
-[backends]
-  [backends.backend1]
-    # ...
-  [backends.backend2]
-    # ...
-
-[frontends]
-  [frontends.frontend1]
-  # ...
-  [frontends.frontend2]
-  # ...
-  [frontends.frontend3]
-  # ...
-
-# HTTPS certificate
-[[tls]]
-  # ...
-
-[[tls]]
-  # ...
-```
-
-!!! note
-    adding certificates directly to the entrypoint is still maintained but certificates declared in this way cannot be managed dynamically.
-    It's recommended to use the file provider to declare certificates.
-
-### Rules in a Separate File
-
-Put your rules in a separate file, for example `rules.toml`:
-
-```toml
-# traefik.toml
-defaultEntryPoints = ["http", "https"]
-
-[entryPoints]
-  [entryPoints.http]
-    # ...
-  [entryPoints.https]
-    # ...
-
-[file]
-  filename = "rules.toml"
-```
-
-```toml
-# rules.toml
-[backends]
-  [backends.backend1]
-    # ...
-  [backends.backend2]
-    # ...
-
-[frontends]
-  [frontends.frontend1]
-  # ...
-  [frontends.frontend2]
-  # ...
-  [frontends.frontend3]
-  # ...
-
-# HTTPS certificate
-[[tls]]
-  # ...
-
-[[tls]]
-  # ...
-```
-
-### Multiple `.toml` Files
-
-You could have multiple `.toml` files in a directory (and recursively in its sub-directories):
-
-```toml
-[file]
-  directory = "/path/to/config/"
-```
-
-If you want Træfik to watch file changes automatically, just add:
-
-```toml
-[file]
-  watch = true
-```
