-We love all the wonderful ideas that our users come up with, but we can only build so much.
-Luckily, as an open source community, our users can help by [building awesome features](https://github.com/orgs/traefik/projects/9/views/7), enhancements, or bug fixes.
-We are a big community, so we do need to prioritize a bit.
-That is why we use the tag `contributor/wanted` to let you know which pull requests will make it to the front of the queue for design support and review.
-Feel free to grab one of these and run with it.

 ## 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 `dep` dependency management tool is required.
 
 ### Method 1: Using `Docker` and `Makefile`
 
 Run make with the `binary` target.
-
-```bash
-make binary
-```
-
 This will create binaries for the Linux platform in the `dist` folder.
 
 In case when you run build on CI, you may probably want to run docker in non-interactive mode. To achieve that define `DOCKER_NON_INTERACTIVE=true` environment variable.

-## How We Prioritize
-
-We wish we could review every pull request right away. 
-Unfortunately, our team has to prioritize pull requests (PRs) for review 
-(but we are welcoming new [maintainers](https://github.com/traefik/traefik/blob/master/docs/content/contributing/maintainers-guidelines.md) to speed this up, 
-so if you are interested, check it out and apply). 
-
-The PRs we are able to handle fastest are:
-
-* Documentation updates.
-* Bug fixes.
-* Enhancements and Features with a `contributor/wanted` tag.
-
-PRs that take more time to address include:
-
-* Enhancements or Features without the `contributor/wanted` tag.  
-  
-If you have an idea for an enhancement or feature that you would like to build, 
-[create an issue](https://github.com/traefik/traefik/issues/new/choose) for it first 
-and tell us you are interested in writing the PR. 
-If an issue already exists, definitely comment on it to tell us you are interested in creating a PR. 
-
-This will allow us to communicate directly and let you know if it is something we would accept. 
-It also allows us to make sure you have all the information you need during the design phase 
-so that it can be reviewed and merged quickly. 
-  
-If you have questions about the Triage process,
-[read more here](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md).  
-  
-## The Pull Request Submit Process
-
-Merging a PR requires the following steps to be completed before it is merged automatically.
-
-* Make sure your pull request adheres to our best practices. These include:
-    * [Following project conventions](https://github.com/traefik/traefik/blob/master/docs/content/contributing/maintainers-guidelines.md); including using the PR Template.
-    * Make small pull requests.
-    * Solve only one problem at a time.
-    * Comment thoroughly.
-    * Do not open the PR from an organization repository.
-    * Keep "allows edit from maintainer" checked.
-    * Use semantic line breaks for documentation.
-* Pass the validation check.
-* Pass all tests.
-* Receive 3 approving reviews maintainers.
-
-## Pull Request Review Cycle
-
-You can read about our Triage Process [here](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md), 
-but in short, it looks like this:
-
-* We triage every new PR or comment before entering it into the review process.
-    * We ensure that all prerequisites for review have been met.
-    * We check to make sure the use case meets our needs.
-    * We assign reviewers.
-* Design Review.
-    * This takes longer than other parts of the process.
-    * We review that there are no obvious conflicts with our codebase.
-* Code Review.
-    * We review the code in-depth and run tests.
-    * We may ask for changes here.
-    * During code review, we ask that you be reasonably responsive, 
-      if a PR languishes in code review it is at risk of rejection, 
-      or we may take ownership of the PR and the contributor will become a co-author.
-* Merge. 
-    * Success!
-
-!!! note
-
-    Occasionally, we may freeze our codebase when working towards a specific feature or goal that could impact other development. 
-    During this time, your pull request could remain unmerged while the release work is completed.
-
-## Run Local Verifications
-
-You must run these local verifications before you submit your pull request to predict the pass or failure of continuous integration. 
-Your PR will not be reviewed until these are green on the CI.
-
-* `make validate`
-* `make pull-images`
-* `make test`
-
-## The Testing and Merge Workflow
-
-Pull Requests are managed by the bot [Myrmica Lobicornis](https://github.com/traefik/lobicornis). 
-This bot is responsible for verifying GitHub Checks (CI, Tests, etc), mergability, and minimum reviews. 
-In addition, it rebases or merges with the base PR branch if needed. 
-It performs several other housekeeping items 
-and you can read more about those on the [README](https://github.com/traefik/lobicornis) for Lobicornis.
-
-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.
-
-The status `status/4-merge-in-progress` is only used by the bot.
-
-If the bot is not able to perform the merge, the label `bot/need-human-merge` is added. 
-In such a situation, solve the conflicts/CI/... and then remove the label `bot/need-human-merge`.
-
-To prevent the bot from automatically merging a PR, add the label `bot/no-merge`.
-
-The label `bot/light-review` decreases the number of required LGTM from 3 to 1.
-
-This label can be used when:
-
-* Updating a dependency.
-* Merging branches back into the next version branch.
-* Submitting minor documentation changes.
-* Submitting changelog PRs.
-
-## Why Was My Pull Request Closed?
-
-Traefik Proxy is made by the community for the community, 
-as such the goal is to engage the community to make Traefik the best reverse proxy available. 
-Part of this goal is maintaining a lean codebase and ensuring code velocity. 
-unfortunately, this means that sometimes we will not be able to merge a pull request.
-
-Because we respect the work you did, you will always be told why we are closing your pull request. 
-If you do not agree with our decision, do not worry; closed pull requests are easy to recreate, 
-and little work is lost by closing a pull request that subsequently needs to be reopened.
-
-Your pull request might be closed if:
-
-* Your PR's design conflicts with our existing codebase in such a way that Merging is not an option 
-  and the work needed to make your pull request usable is too high.
-    * To prevent this, make sure you created an issue first
-      and think about including Traefik Proxy maintainers in your design phase to minimize conflicts.
-* Your PR is for an enhancement or feature that we will not use.
-    * Please remember to create an issue for any pull request **before** you create a PR 
-      to ensure that your goal is something we can merge and that you have any design insight you might need from the team.
-* Your PR has been waiting for feedback from the contributor for over 90 days.
-
-## Why is My Pull Request Not Getting Reviewed
-
-A few factors affect how long your pull request might wait for review.
-
-We must prioritize which PRs we focus on. 
-Our first priority is PRs we have identified as having high community engagement and broad applicability. 
-We put our top priorities on our roadmap and you can identify them by the `contributor/wanted` tag. 
-These PRs will enter our review process the fastest. 
-
-Our second priority is bug fixes. 
-Especially for bugs that have already been tagged with `bug/confirmed`. 
-These reviews enter the process quickly.
-
-If your PR does not meet the criteria above, 
-it will take longer for us to review as any PRs that do meet the criteria above will be prioritized. 
-
-Additionally, during the last few weeks of a milestone, we stop reviewing PRs to reduce churn and stabilize. 
-We will resume after the release. 
-
-The second major reason that we deprioritize your PR is that you are not following best practices. 
-
-The most common failures to follow best practices are:
-
-* You did not create an issue for the PR you wish to make. 
-  If you do not create an issue before submitting your PR, 
-  we will not be able to answer any design questions and let you know how likely your PR is to be merged. 
-* You created pull requests that are too large to review.
-    * Break your pull requests up.
-      If you can extract whole ideas from your pull request and send those as pull requests of their own, 
-      you should do that instead. 
-      It is better to have many pull requests addressing one thing than one pull request addressing many things. 
-    * Traefik Proxy is a fast-moving codebase — lock in your changes ASAP with your small pull request, 
-      and make merges be someone else's problem.
-      We want every pull request to be useful on its own, 
-      so use your best judgment on what should be a pull request vs. a commit.
-* You did not comment well.
-    * Comment everything.
-
-Please remember that we are working internationally, cross-culturally, and with different use-cases. 
-Your reviewer will not intuitively understand the problem the same way you do or solve it the same way you would.
-This is why every change you make must be explained and your strategy for coding must also be explained.   
-
-* Your tests were inadequate or absent.
-    * If you do not know how to test your PR, please ask! 
-      We will be happy to help you or suggest appropriate test cases.
-
-If you have already followed the best practices and your PR still has not received a response, 
-here are some things you can do to move the process along:
-
-* If you have fixed all the issues from a review, 
-  remember to re-request a review (using the designated button) to let your reviewer know that you are ready. 
-  You can choose to comment with the changes you made. 
-* Ping `@tfny` if you have not been assigned to a reviewer.
-

-
-## It's OK to Push Back
-
-Sometimes reviewers make mistakes. 
-It is OK to push back on changes your reviewer requested. 
-If you have a good reason for doing something a certain way, you are absolutely allowed to debate the merits of a requested change.
-Both the reviewer and reviewee should strive to discuss these issues in a polite and respectful manner.
-
-You might be overruled, but you might also prevail. 
-We are pretty reasonable people.
-
-Another phenomenon of open-source projects (where anyone can comment on any issue) is the dog-pile -
-your pull request gets so many comments from so many people it becomes hard to follow. 
-In this situation, you can ask the primary reviewer (assignee) whether they want you to fork a new pull request 
-to clear out all the comments. 
-You do not have to fix every issue raised by every person who feels like commenting, 
-but you should answer reasonable comments with an explanation.
-
-## Common Sense and Courtesy
-
-No document can take the place of common sense and good taste. 
-Use your best judgment, while you put a bit of thought into how your work can be made easier to review. 
-If you do these things your pull requests will get merged with less friction.

-The "field not found" error occurs, when an unknown property is encountered in the dynamic or static configuration.

-
-# Quick Start
-
-A Simple Use Case of Traefik Proxy and Kubernetes
-{: .subtitle }
-
-This guide is an introduction to using Traefik Proxy in a Kubernetes environment.
-The objective is to learn how to run an application behind a Traefik reverse proxy in Kubernetes.
-It presents and explains the basic blocks required to start with Traefik such as Ingress Controller, Ingresses, Deployments, static, and dynamic configuration.
-
-## Permissions and Accesses
-
-Traefik uses the Kubernetes API to discover running services.
-
-In order to use the Kubernetes API, Traefik needs some permissions.
-This [permission mechanism](https://kubernetes.io/docs/reference/access-authn-authz/rbac/) is based on roles defined by the cluster administrator.
-The role is then bound to an account used by an application, in this case, Traefik Proxy.
-
-The first step is to create the role.
-The [`ClusterRole`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-v1/#ClusterRole) resource enumerates the resources and actions available for the role.
-In a file called `00-role.yml`, put the following `ClusterRole`:
-
-```yaml tab="00-role.yml"
-kind: ClusterRole
-apiVersion: rbac.authorization.k8s.io/v1
-metadata:
-  name: traefik-role
-
-rules:
-  - apiGroups:
-      - ""
-    resources:
-      - services
-      - endpoints
-      - secrets
-    verbs:
-      - get
-      - list
-      - watch
-  - apiGroups:
-      - extensions
-      - networking.k8s.io
-    resources:
-      - ingresses
-      - ingressclasses
-    verbs:
-      - get
-      - list
-      - watch
-  - apiGroups:
-      - extensions
-      - networking.k8s.io
-    resources:
-      - ingresses/status
-    verbs:
-      - update
-```
-
-!!! info "You can find the reference for this file [there](../../reference/dynamic-configuration/kubernetes-crd/#rbac)."
-
-The next step is to create a dedicated service account for Traefik.
-In a file called `00-account.yml`, put the following [`ServiceAccount`](https://kubernetes.io/docs/reference/kubernetes-api/authentication-resources/service-account-v1/#ServiceAccount) resource:
-
-```yaml tab="00-account.yml"
-apiVersion: v1
-kind: ServiceAccount
-metadata:
-  name: traefik-account
-```
-
-And then, bind the role on the account to apply the permissions and rules on the latter. In a file called `01-role-binding.yml`, put the
-following [`ClusterRoleBinding`](https://kubernetes.io/docs/reference/kubernetes-api/authorization-resources/cluster-role-binding-v1/#ClusterRoleBinding) resource:
-
-```yaml tab="01-role-binding.yml"
-kind: ClusterRoleBinding
-apiVersion: rbac.authorization.k8s.io/v1
-metadata:
-  name: traefik-role-binding
-
-roleRef:
-  apiGroup: rbac.authorization.k8s.io
-  kind: ClusterRole
-  name: traefik-role
-subjects:
-  - kind: ServiceAccount
-    name: traefik-account
-    namespace: default # Using "default" because we did not specify a namespace when creating the ClusterAccount.
-```
-
-!!! info "`roleRef` is the Kubernetes reference to the role created in `00-role.yml`."
-
-!!! info "`subjects` is the list of accounts reference."
-
-    In this guide, it only contains the account created in `00-account.yml`
-
-## Deployment and Exposition
-
-!!! info "This section can be managed with the help of the [Traefik Helm chart](../install-traefik/#use-the-helm-chart)."
-
-The [ingress controller](https://traefik.io/glossary/kubernetes-ingress-and-ingress-controller-101/#what-is-a-kubernetes-ingress-controller)
-is a software that runs in the same way as any other application on a cluster.
-To start Traefik on the Kubernetes cluster,
-a [`Deployment`](https://kubernetes.io/docs/reference/kubernetes-api/workload-resources/deployment-v1/) resource must exist to describe how to configure
-and scale containers horizontally to support larger workloads.
-
-Start by creating a file called `02-traefik.yml` and paste the following `Deployment` resource:
-
-```yaml tab="02-traefik.yml"
-kind: Deployment
-apiVersion: apps/v1
-metadata:
-  name: traefik-deployment
-  labels:
-    app: traefik
-
-spec:
-  replicas: 1
-  selector:
-    matchLabels:
-      app: traefik
-  template:
-    metadata:
-      labels:
-        app: traefik
-    spec:
-      serviceAccountName: traefik-account
-      containers:
-        - name: traefik
-          image: traefik:v3.0
-          args:
-            - --api.insecure
-            - --providers.kubernetesingress
-          ports:
-            - name: web
-              containerPort: 80
-            - name: dashboard
-              containerPort: 8080
-```
-
-The deployment contains an important attribute for customizing Traefik: `args`.
-These arguments are the static configuration for Traefik.
-From here, it is possible to enable the dashboard,
-configure entry points,
-select dynamic configuration providers,
-and [more](../reference/static-configuration/cli.md)...
-
-In this deployment,
-the static configuration enables the Traefik dashboard,
-and uses Kubernetes native Ingress resources as router definitions to route incoming requests.
-
-!!! info "When there is no entry point in the static configuration"
-
-    Traefik creates a default one called `web` using the port `80` routing HTTP requests.
-
-!!! info "When enabling the [`api.insecure`](../../operations/api/#insecure) mode, Traefik exposes the dashboard on the port `8080`."
-
-A deployment manages scaling and then can create lots of containers, called [Pods](https://kubernetes.io/docs/concepts/workloads/pods/).
-Each Pod is configured following the `spec` field in the deployment.
-Given that, a Deployment can run multiple Traefik Proxy Pods,
-a piece is required to forward the traffic to any of the instance:
-namely a [`Service`](https://kubernetes.io/docs/reference/kubernetes-api/service-resources/service-v1/#Service).
-Create a file called `02-traefik-services.yml` and insert the two `Service` resources:
-
-```yaml tab="02-traefik-services.yml"
-apiVersion: v1
-kind: Service
-metadata:
-  name: traefik-dashboard-service
-
-spec:
-  type: LoadBalancer
-  ports:
-    - port: 8080
-      targetPort: dashboard
-  selector:
-    app: traefik
----
-apiVersion: v1
-kind: Service
-metadata:
-  name: traefik-web-service
-
-spec:
-  type: LoadBalancer
-  ports:
-    - targetPort: web
-      port: 80
-  selector:
-    app: traefik
-```
-
-!!! warning "It is possible to expose a service in different ways."
-
-    Depending on your working environment and use case, the `spec.type` might change.
-    It is strongly recommended to understand the available [service types](https://kubernetes.io/docs/concepts/services-networking/service/#publishing-services-service-types) before proceeding to the next step.
-
-It is now time to apply those files on your cluster to start Traefik.
-
-```shell
-kubectl apply -f 00-role.yml \
-              -f 00-account.yml \
-              -f 01-role-binding.yml \
-              -f 02-traefik.yml \
-              -f 02-traefik-services.yml
-```
-
-## Proxying applications
-
-The only part still missing is the business application behind the reverse proxy.
-For this guide, we use the example application [traefik/whoami](https://github.com/traefik/whoami),
-but the principles are applicable to any other application.
-
-The `whoami` application is a simple HTTP server running on port 80 which answers host-related information to the incoming requests.
-As usual, start by creating a file called `03-whoami.yml` and paste the following `Deployment` resource:
-
-```yaml tab="03-whoami.yml"
-kind: Deployment
-apiVersion: apps/v1
-metadata:
-  name: whoami
-  labels:
-    app: whoami
-
-spec:
-  replicas: 1
-  selector:
-    matchLabels:
-      app: whoami
-  template:
-    metadata:
-      labels:
-        app: whoami
-    spec:
-      containers:
-        - name: whoami
-          image: traefik/whoami
-          ports:
-            - name: web
-              containerPort: 80
-```
-
-And continue by creating the following `Service` resource in a file called `03-whoami-services.yml`:
-
-```yaml tab="03-whoami-services.yml"
-apiVersion: v1
-kind: Service
-metadata:
-  name: whoami
-
-spec:
-  ports:
-    - name: web
-      port: 80
-      targetPort: web
-      
-  selector:
-    app: whoami
-```
-
-Thanks to the Kubernetes API,
-Traefik is notified when an Ingress resource is created, updated, or deleted.
-This makes the process dynamic.
-The ingresses are, in a way, the [dynamic configuration](../../providers/kubernetes-ingress/) for Traefik.
-
-!!! tip
-
-    Find more information on [ingress controller](https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/),
-    and [Ingress](https://kubernetes.io/docs/concepts/services-networking/ingress/) in the official Kubernetes documentation.
-
-Create a file called `04-whoami-ingress.yml` and insert the `Ingress` resource:
-
-```yaml tab="04-whoami-ingress.yml"
-apiVersion: networking.k8s.io/v1
-kind: Ingress
-metadata:
-  name: whoami-ingress
-spec:
-  rules:
-  - http:
-      paths:
-      - path: /
-        pathType: Prefix
-        backend:
-          service:
-            name: whoami
-            port:
-              name: web
-```
-
-This `Ingress` configures Traefik to redirect any incoming requests starting with `/` to the `whoami:80` service.
-
-At this point, all the configurations are ready.
-It is time to apply those new files:
-
-```shell
-kubectl apply -f 03-whoami.yml \
-              -f 03-whoami-services.yml \
-              -f 04-whoami-ingress.yml
-```
-
-Now you should be able to access the `whoami` application and the Traefik dashboard.
-Load the dashboard on a web browser: [`http://localhost:8080`](http://localhost:8080).
-
-And now access the `whoami` application:
-
-```shell
-curl -v http://localhost/
-```
-
-!!! question "Going further"
-
-    - [Filter the ingresses](../providers/kubernetes-ingress.md#ingressclass) to use with [IngressClass](https://kubernetes.io/docs/concepts/services-networking/ingress/#ingress-class)
-    - Use [IngressRoute CRD](../providers/kubernetes-crd.md)
-    - Protect [ingresses with TLS](../routing/providers/kubernetes-ingress.md#enabling-tls-via-annotations)

-
-Secure the backend connection with SPIFFE.
-{: .subtitle }
-
-[SPIFFE](https://spiffe.io/docs/latest/spiffe-about/overview/) (Secure Production Identity Framework For Everyone), 
-provides a secure identity in the form of a specially crafted X.509 certificate, 
-to every workload in an environment.
-
-Traefik is able to connect to the Workload API to obtain an x509-SVID used to secure the connection with SPIFFE enabled backends.
-
-## Configuration
-
-### General
-
-Enabling SPIFFE is part of the [static configuration](../getting-started/configuration-overview.md#the-static-configuration).
-It can be defined by using a file (YAML or TOML) or CLI arguments.
-
-### Workload API
-
-The `workloadAPIAddr` configuration defines the address of the SPIFFE [Workload API](https://spiffe.io/docs/latest/spiffe-about/spiffe-concepts/#spiffe-workload-api).
-
-!!! info "Enabling SPIFFE in ServersTransports"
-
-    Enabling SPIFFE does not imply that backend connections are going to use it automatically.
-    Each [ServersTransport](../routing/services/index.md#serverstransport_1) that is meant to be secured with SPIFFE must [explicitly](../routing/services/index.md#spiffe) enable it.
-
-!!! warning "SPIFFE can cause Traefik to stall"
-	When using SPIFFE,
-	Traefik will wait for the first SVID to be delivered before starting.
-	If Traefik is hanging when waiting on SPIFFE SVID delivery,
-	please double check that it is correctly registered as workload in your SPIFFE infrastructure.

-# Tailscale
-
-Provision TLS certificates for your internal Tailscale services.
-{: .subtitle }
-
-To protect a service with TLS, a certificate from a public Certificate Authority is needed.
-In addition to its vpn role, Tailscale can also [provide certificates](https://tailscale.com/kb/1153/enabling-https/) for the machines in your Tailscale network.
-
-## Certificate resolvers
-
-To obtain a TLS certificate from the Tailscale daemon,
-a Tailscale certificate resolver needs to be configured as below.
-
-!!! info "Referencing a certificate resolver"
-
-    Defining a certificate resolver does not imply that routers are going to use it automatically.
-    Each router or entrypoint that is meant to use the resolver must explicitly [reference](../routing/routers/index.md#certresolver) it.
-
-```yaml tab="File (YAML)"
-certificatesResolvers:
-    myresolver:

-```
-
-```bash tab="CLI"
---certificatesresolvers.myresolver.tailscale=true
-```
-
-## Domain Definition
-
-A certificate resolver requests certificates for a set of domain names inferred from routers, according to the following:
-
-- If the router has a [`tls.domains`](../routing/routers/index.md#domains) option set,
-  then the certificate resolver derives this router domain name from the `main` option of `tls.domains`.
-
-- Otherwise, the certificate resolver derives the domain name from any `Host()` or `HostSNI()` matchers
-  in the [router's rule](../routing/routers/index.md#rule).
-
-!!! info "Tailscale Domain Format"
-
-    The domain is only taken into account if it is a Tailscale-specific one,
-    i.e. of the form `machine-name.domains-alias.ts.net`.
-

-The Content-Type middleware sets the `Content-Type` header value to the media type detected from the response content,
-when it is not set by the backend.
+The Content-Type middleware - or rather its `autoDetect` option -
+specifies whether to let the `Content-Type` header,
+if it has not been defined by the backend,
+be automatically set to a value derived from the contents of the response.
+
+As a proxy, the default behavior should be to leave the header alone,
+regardless of what the backend did with it.
+However, the historic default was to always auto-detect and set the header if it was not already defined,
+and altering this behavior would be a breaking change which would impact many users.
+
+This middleware exists to enable the correct behavior until at least the default one can be changed in a future version.
 
 !!! info
 
+    As explained above, for compatibility reasons the default behavior on a router (without this middleware),
+    is still to automatically set the `Content-Type` header.
+    Therefore, given the default value of the `autoDetect` option (false),
+    simply enabling this middleware for a router switches the router's behavior.
+
     The scope of the Content-Type middleware is the MIME type detection done by the core of Traefik (the server part).
     Therefore, it has no effect against any other `Content-Type` header modifications (e.g.: in another middleware such as compress).

-# Migration Guide: From v2 to v3
-
-How to Migrate from Traefik v2 to Traefik v3.
-{: .subtitle }
-
-The version 3 of Traefik introduces a number of breaking changes,
-which require one to update their configuration when they migrate from v2 to v3.
-The goal of this page is to recapitulate all of these changes, and in particular to give examples,
-feature by feature, of how the configuration looked like in v2, and how it now looks like in v3.
-
-## IPWhiteList
-
-In v3, we renamed the `IPWhiteList` middleware to `IPAllowList` without changing anything to the configuration. 
-
-## gRPC Metrics
-
-In v3, the reported status code for gRPC requests is now the value of the `Grpc-Status` header.  
-
-## Deprecated Options Removal
-
-- The `pilot` option has been removed from the static configuration.
-- The `tracing.datadog.globaltag` option has been removed.
-- The `namespace` option of Consul, Consul Catalog and Nomad providers has been removed.
-- The `tls.caOptional` option has been removed from the ForwardAuth middleware, as well as from the HTTP, Consul, Etcd, Redis, ZooKeeper, Marathon, Consul Catalog, and Docker providers.
-- `sslRedirect`, `sslTemporaryRedirect`, `sslHost`, `sslForceHost` and `featurePolicy` options of the Headers middleware have been removed.
-- The `forceSlash` option of the StripPrefix middleware has been removed.
-- the `preferServerCipherSuites` option has been removed.
-
-## Matchers
-
-In v3, the `Headers` and `HeadersRegexp` matchers have been renamed to `Header` and `HeaderRegexp` respectively.
-
-`QueryRegexp` has been introduced to match query values using a regular expression.
-
-`HeaderRegexp`, `HostRegexp`, `PathRegexp`, `QueryRegexp`, and `HostSNIRegexp` matchers now uses the [Go regexp syntax](https://golang.org/pkg/regexp/syntax/).
-
-All matchers now take a single value (except `Headers`, `HeaderRegexp`, `Query`, and `QueryRegexp` which take two)
-and should be explicitly combined using logical operators to mimic previous behavior.
-
-`Query` can take a single value to match is the query value that has no value (e.g. `/search?mobile`).
-
-`HostHeader` has been removed, use `Host` instead.
-
-## Content-Type Auto-Detection
-
-In v3, the `Content-Type` header is not auto-detected anymore when it is not set by the backend.
-One should use the `ContentType` middleware to enable the `Content-Type` header value auto-detection.
-
-## HTTP/3
-
-In v3, HTTP/3 is no longer an experimental feature.
-The `experimental.http3` option has been removed from the static configuration.

+# Plugins and Traefik Pilot
 
-Plugins are a powerful feature for extending Traefik with custom features and behaviors.
-The [Plugin Catalog](https://plugins.traefik.io/) is a software-as-a-service (SaaS) platform that provides an exhaustive list of the existing plugins.
+Traefik Pilot is a software-as-a-service (SaaS) platform that connects to Traefik to extend its capabilities.
+It offers a number of features to enhance observability and control of Traefik through a global control plane and dashboard, including:
 
-??? note "Plugin Catalog Access"
-    You can reach the [Plugin Catalog](https://plugins.traefik.io/) from the Traefik Dashboard using the `Plugins` menu entry.
+* Metrics for network activity of Traefik proxies and groups of proxies
+* Alerts for service health issues and security vulnerabilities
+* Plugins that extend the functionality of Traefik
 
-To add a new plugin to a Traefik instance, you must change that instance's static configuration.
-Each plugin's **Install** section provides a static configuration example.
-Many plugins have their own section in the Traefik dynamic configuration.
+!!! important "Learn More About Traefik Pilot"
+    This section is intended only as a brief overview for Traefik users who are not familiar with Traefik Pilot. 
+    To explore all that Traefik Pilot has to offer, please consult the [Traefik Pilot Documentation](https://doc.traefik.io/traefik-pilot/)
 
-To learn more about Traefik plugins, consult the [documentation](https://plugins.traefik.io/install).
+!!! Note "Prerequisites"
+    Traefik Pilot is compatible with Traefik Proxy 2.3 or later.
+
+## Connecting to Traefik Pilot
+
+To connect your Traefik proxies to Traefik Pilot, login or create an account at the [Traefik Pilot homepage](https://pilot.traefik.io) and choose **Register New Traefik Instance**.
+
+To complete the connection, Traefik Pilot will issue a token that must be added to your Traefik static configuration, according to the instructions provided by the Traefik Pilot dashboard.
+For more information, consult the [Quick Start Guide](https://doc.traefik.io/traefik-pilot/connecting/)
+
+Health and security alerts for registered Traefik instances can be enabled from the Preferences in your [Traefik Pilot Profile](https://pilot.traefik.io/profile).
+
+## Plugins
+
+Plugins are available to any Traefik proxies that are connected to Traefik Pilot.
+They are a powerful feature for extending Traefik with custom features and behaviors.
+
+You can browse community-contributed plugins from the catalog in the [Traefik Pilot Dashboard](https://pilot.traefik.io/plugins).
+
+To add a new plugin to a Traefik instance, you must modify that instance's static configuration.
+The code to be added is provided for you when you choose **Install the Plugin** from the Traefik Pilot dashboard.
+To learn more about Traefik plugins, consult the [documentation](https://doc.traefik.io/traefik-pilot/plugins/overview/).

-and can include [sprig template functions](https://masterminds.github.io/sprig/).
-The service name can be accessed with the `Name` identifier,
-and the template has access to all the labels (i.e. tags beginning with the `prefix`) defined on this service.

-_Optional, Default=""_
-
-The `constraints` option can be set to an expression that Traefik matches against the service tags to determine whether
-to create any route for that service. If none of the service tags match the expression, no route for that service is
-created. If the expression is empty, all detected services are included.
-
-The expression syntax is based on the ```Tag(`tag`)```, and ```TagRegex(`tag`)``` functions,
-as well as the usual boolean logic, as shown in examples below.
-
-??? example "Constraints Expression Examples"
-
-    ```toml
