-### Building
-
-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 `glide` dependency management tool and `glide-vc` plugin are required.
-
-#### 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:1.7
- ---> 8c6473912976
-Step 1 : RUN go get github.com/Masterminds/glide
-[...]
-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/emile/dev/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` v1.7+
-- 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)
-- This will allow your `GOPATH` and `PATH` variable to be set to `~/go` via:
-```bash
-$ export GOPATH=~/go
-$ export PATH=$PATH:$GOPATH/bin
-```
-
-This can be verified via `$ go env`
-- You will want to add those 2 export lines to your `.bashrc` or `.bash_profile`
-- You need `go-bindata` to be able to use `go generate` command (needed to build) : `$ go get github.com/jteeuwen/go-bindata/...` (Please note, the ellipses are required)
-
-#### Setting up `glide` and `glide-vc` for dependency management
-
-- Glide is not required for building; however, it is necessary to modify dependencies (i.e., add, update, or remove third-party packages)
-- Glide can be installed either via homebrew: `$ brew install glide` or via the official glide script: `$ curl https://glide.sh/get | sh`
-- The glide plugin `glide-vc` must be installed from source: `go get github.com/sgotti/glide-vc`
-
-If you want to add a dependency, use `$ glide get` to have glide put it into the vendor folder and update the glide manifest/lock files (`glide.yaml` and `glide.lock`, respectively). A following `glide-vc` run should be triggered to trim down the size of the vendor folder. The final result must be committed into VCS.
-
-Dependencies for the integration tests in the `integration` folder are managed in a separate `integration/glide.yaml` file using the same toolset.
-
-Care must be taken to choose the right arguments to `glide` when dealing with either main or integration test dependencies, or otherwise risk ending up with a broken build. For that reason, the helper script `script/glide.sh` encapsulates the gory details and conveniently calls `glide-vc` as well. Call it without parameters for basic usage instructions.
-
-Here's a full example:
-
-```bash
-# install the new main dependency github.com/foo/bar and minimize vendor size
-$ ./script/glide.sh get github.com/foo/bar
-# install another dependency, this time for the integration tests
-$ ( cd integration && ../script/glide.sh get github.com/baz/quuz )
-# generate (Only required to integrate other components such as web dashboard)
-$ go generate
-# Standard go build
-$ go build
-# Using gox to build multiple platform
-$ gox "linux darwin" "386 amd64 arm" \
-    -output="dist/traefik_{{.OS}}-{{.Arch}}" \
-    ./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/vincent/src/github/vdemeester/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`
-
-- Tests can be run from the cloned directory, by `$ go test ./...` which should return `ok` similar to:
-```
-ok      _/home/vincent/src/github/vdemeester/traefik    0.004s
-```
-
-### Documentation
-
-The [documentation site](http://docs.traefik.io/) is built with [mkdocs](http://mkdocs.org/)
-
-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 mkdocs
-```
-
-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

+Traefik (pronounced _traffic_) is a modern HTTP reverse proxy and load balancer that makes deploying microservices easy.
+Traefik integrates with your existing infrastructure components ([Docker](https://www.docker.com/), [Swarm mode](https://docs.docker.com/engine/swarm/), [Kubernetes](https://kubernetes.io), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Rancher v2](https://rancher.com), [Amazon ECS](https://aws.amazon.com/ecs), ...) and configures itself automatically and dynamically.
+Pointing Traefik at your orchestrator should be the _only_ configuration step you need.
 
-Træfik (pronounced like [traffic](https://speak-ipa.bearbin.net/speak.cgi?speak=%CB%88tr%C3%A6f%C9%AAk)) is a modern HTTP reverse proxy and load balancer made to deploy microservices with ease.
-It supports several backends ([Docker](https://www.docker.com/), [Swarm](https://docs.docker.com/swarm), [Kubernetes](http://kubernetes.io), [Marathon](https://mesosphere.github.io/marathon/), [Mesos](https://github.com/apache/mesos), [Consul](https://www.consul.io/), [Etcd](https://coreos.com/etcd/), [Zookeeper](https://zookeeper.apache.org), [BoltDB](https://github.com/boltdb/bolt), [Eureka](https://github.com/Netflix/eureka), [Amazon DynamoDB](https://aws.amazon.com/dynamodb/), Rest API, file...) to manage its configuration automatically and dynamically.

+:warning: Please be aware that the old configurations for Traefik v1.x are NOT compatible with the v2.x config as of now. If you're running v2, please ensure you are using a [v2 configuration](https://doc.traefik.io/traefik/).
 
 ## 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. 
 
-But a microservices architecture is dynamic... Services are added, removed, killed or upgraded often, eventually several 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
+
+- We usually release 3/4 new versions (e.g. 1.1.0, 1.2.0, 1.3.0) per year.
+- Release Candidates are available before the release (e.g. 1.1.0-rc1, 1.1.0-rc2, 1.1.0-rc3, 1.1.0-rc4, before 1.1.0).
+- Bug-fixes (e.g. 1.1.1, 1.1.2, 1.2.1, 1.2.3) are released as needed (no additional features are delivered in those versions, bug-fixes only).
+
+Each version is supported until the next one is released (e.g. 1.1.x will be supported until 1.2.0 is out).
+
+We use [Semantic Versioning](https://semver.org/).

-# Concepts
-
-Let's take our example from the [overview](https://docs.traefik.io/#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]
-  clientCAFiles = ["tests/clientca1.crt", "tests/clientca2.crt"]
-    [[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.
-
-### 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).
-
-You can optionally enable `passHostHeader` to forward client `Host` header to the backend.
-
-Following is the list of existing matcher rules along with examples:
-
-- `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.
-
-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 that the variable has no special meaning; however, it is required by the gorilla/mux dependency which embeds the regular expression and defines the syntax.)
-
-#### 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
-  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`).
-
-## 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 range [500-600) to  [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 are supported with both load balancers. When sticky sessions are enabled, a cookie called `_TRAEFIK_BACKEND` is set on the initial
-request. 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.
-
-For example:
-```toml
-[backends]
-  [backends.backend1]
-    [backends.backend1.loadbalancer]
-      sticky = true
-```
-
-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 path
-appended 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.
-
-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"
-```
-
-## 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).
-
-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-trfk-configuration) which is loaded only at the beginning. 
-- The [dynamic Træfik configuration](/basics#dynamic-trfk-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.
-
-### 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](/toml/#global-configuration) 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) 
-
-Træfik can hot-reload those rules which could be provided by [multiple configuration backends](/toml/#configuration-backends).
-
-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](/toml/#configuration-backends) section to get documentation on it.
-
-# Commands
-
-Usage: `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-trfk-configuration) section to get documentation on it.
-
-Each command may have related flags. 
-All those related flags will be displayed with :
-
-```bash
-$ traefik [command] --help
-```
-
-Note that each command is described at the beginning of the help section:
-
-```bash
-$ traefik --help

-## 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)
