+Issues and PRs are triaged daily and the process for triaging may be found under [triaging issues](https://github.com/traefik/contributors-guide/blob/master/issue_triage.md) in our [contributors guide repository](https://github.com/traefik/contributors-guide).
 
 ## PR review process:
 
-* The status `needs-design-review` is only used in complex/heavy/tricky PRs.
-* From `1` to `2`: 1 comment that says “design LGTM” (by a senior maintainer).
-* From `2` to `3`: 3 LGTM approvals by any maintainer.
-* If needed, a specific maintainer familiar with a particular domain can be requested for the review.
-* If a PR has been implemented in pair programming, one peer's LGTM goes into the review for free
-* Amending someone else's pull request is authorized only in emergency, if a rebase is needed, or if the initial contributor is silent
-
-We use [PRM](https://github.com/ldez/prm) to manage locally pull requests.
-
-## 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.
-To preserve commits, add `bot/merge-method-rebase` before `status/3-needs-merge`.
-
-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 is used when:
-
-* Updating the vendors from previously reviewed PRs
-* Merging branches into the master
-* Preparing the release
-
-### [Myrmica Bibikoffi](https://github.com/containous/bibikoffi/)
-
-* closes stale issues [cron]
-    * use some criterion as number of days between creation, last update, labels, ...
-
-### [Myrmica Aloba](https://github.com/containous/aloba)
-
-Manage GitHub labels.
-
-* Add labels on new PR [GitHub WebHook]
-* Add milestone to a new PR based on a branch version (1.4, 1.3, ...) [GitHub WebHook]
-* Add and remove `contributor/waiting-for-corrections` label when a review request changes [GitHub WebHook]
-* Weekly report of PR status on Slack (CaptainPR) [cron]
+The process for reviewing PRs may be found under [review guidelines](https://github.com/traefik/contributors-guide/blob/master/review_guidelines.md) in our contributors guide repository.

+### Exposing the Traefik dashboard
+
+This HelmChart does not expose the Traefik dashboard by default, for security concerns.
+Thus, there are multiple ways to expose the dashboard.
+For instance, the dashboard access could be achieved through a port-forward :
+
+```shell
+kubectl port-forward $(kubectl get pods --selector "app.kubernetes.io/name=traefik" --output=name) 9000:9000
+```
+
+Accessible with the url: http://127.0.0.1:9000/dashboard/
+
+Another way would be to apply your own configuration, for instance,
+by defining and applying an IngressRoute CRD (`kubectl apply -f dashboard.yaml`):
+
+```yaml
+# dashboard.yaml
+apiVersion: traefik.containo.us/v1alpha1
+kind: IngressRoute
+metadata:
+  name: dashboard
+spec:
+  entryPoints:
+    - web
+  routes:
+    - match: Host(`traefik.localhost`) && (PathPrefix(`/dashboard`) || PathPrefix(`/api`))
+      kind: Rule
+      services:

-## Provider Namespace
-
-When you declare a middleware, it lives in its provider's namespace.
-For example, if you declare a middleware using a Docker label, under the hoods, it will reside in the docker provider namespace.
-
-If you use multiple providers and wish to reference a middleware declared in another provider
-(aka referencing a cross-provider middleware),
-then you'll have to append to the middleware name, the `@` separator, followed by the provider name.
-
-```text
-<resource-name>@<provider-name>
-```
-
-!!! important "Kubernetes Namespace"
-
-    As Kubernetes also has its own notion of namespace, one should not confuse the "provider namespace"
-    with the "kubernetes namespace" of a resource when in the context of a cross-provider usage.
-    In this case, since the definition of the middleware is not in kubernetes,
-    specifying a "kubernetes namespace" when referring to the resource does not make any sense,
-    and therefore this specification would be ignored even if present.

+
+Traefik will timestamp each log line in UTC time by default.
+
+It is possible to configure the Traefik to timestamp in a specific timezone by ensuring the following configuration has been made in your environment:
+
+1. Provide time zone data to `/etc/localtime` or `/usr/share/zoneinfo` (based on your distribution) or set the environment variable TZ to the desired timezone
+2. Specify the field `StartLocal` by dropping the field named `StartUTC` (available on the default Common Log Format (CLF) as well as JSON)

+# Plugins and Traefik Pilot
+
+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:
+
+* 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
+
+!!! 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/)
+
+!!! 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/).
+
+!!! danger "Experimental Features"
+    Plugins can potentially modify the behavior of Traefik in unforeseen ways.
+    Exercise caution when adding new plugins to production Traefik instances.
+
+## Build Your Own Plugins
+
+Traefik users can create their own plugins and contribute them to the Traefik Pilot catalog to share them with the community.
+
+Traefik plugins are loaded dynamically. 
+They need not be compiled, and no complex toolchain is necessary to build them. 
+The experience of implementing a Traefik plugin is comparable to writing a web browser extension.
+
+To learn more and see code for example Traefik plugins, please see the [developer documentation](https://doc.traefik.io/traefik-pilot/plugins/plugin-dev/).

+??? example "Configuring ECS provider"
+
+    Enabling the ECS provider:

+
+If `region` is not provided, it will be resolved from the EC2 metadata endpoint for EC2 tasks. 
+In a FARGATE context it will be resolved from the `AWS_REGION` env variable.
+
+If `accessKeyID` / `secretAccessKey` are not provided, credentials will be resolved in the following order:

+## Provider Namespace
+
+When you declare certain objects, in Traefik dynamic configuration,
+such as middleware, service, TLS options or servers transport, they live in its provider's namespace.
+For example, if you declare a middleware using a Docker label, under the hoods, it will reside in the docker provider namespace.
+
+If you use multiple providers and wish to reference such an object declared in another provider 
+(aka referencing a cross-provider object, e.g. middleware), then you'll have to append the `@` separator, 
+followed by the provider name to the object name.
+
+```text
+<resource-name>@<provider-name>
+```
+
+!!! important "Kubernetes Namespace"
+
+    As Kubernetes also has its own notion of namespace,
+    one should not confuse the "provider namespace" with the "kubernetes namespace" of a resource when in the context of a cross-provider usage.  
+    In this case, since the definition of a traefik dynamic configuration object is not in kubernetes,
+    specifying a "kubernetes namespace" when referring to the resource does not make any sense,
+    and therefore this specification would be ignored even if present.  
+    On the other hand, if you, say, declare a middleware as a Custom Resource in Kubernetes and use the non-crd Ingress objects,
+    you'll have to add the Kubernetes namespace of the middleware to the annotation like this `<middleware-namespace>-<middleware-name>@kubernetescrd`.
