    The values are not (yet) documented, but are self-explanatory:
    you can look at the [default `values.yaml`](https://github.com/containous/traefik-helm-chart/blob/master/traefik/values.yaml) file to explore possibilities.
    
+    You can also set Traefik command line flags using `additionalArguments`.
    Example of installation with logging set to `DEBUG`:
    
    ```bash tab="Using Helm CLI"
    helm install --namespace=traefik-v2 \
-        --set="logs.loglevel=DEBUG" \

-    logs:
-        loglevel: DEBUG
+    additionalArguments:
+      - "--log.level=DEBUG"
    ```
+    
+### 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:
+        - name: api@internal
+          kind: TraefikService
+```

+### InsecureSNI removal
+
+In `v2.2.2` we introduced a new flag (`insecureSNI`) which was available as a global option to disable domain fronting.
+Since `v2.2.5` this global option has been removed, and you should not use it anymore.
+
+### HostSNI rule matcher removal
+
+In `v2.2.2` we introduced a new rule matcher (`HostSNI`) for HTTP routers which was allowing to match the Server Name Indication at the router level.
+Since `v2.2.5` this rule has been removed for HTTP routers, and you should not use it anymore.
+
+## v2.2 to v2.3
+
+### X.509 CommonName Deprecation
+
+The deprecated, legacy behavior of treating the CommonName field on X.509 certificates as a host name when no Subject Alternative Names are present, is now disabled by default.
+
+It means that if one is using https with your backend servers, and a certificate with only a CommonName,
+Traefik will not try to match the server name indication with the CommonName anymore.
+
+It can be temporarily re-enabled by adding the value `x509ignoreCN=0` to the `GODEBUG` environment variable.
+
+More information: https://golang.org/doc/go1.15#commonname
+
+### File Provider
+
+The file parser has been changed, since v2.3 the unknown options/fields in a dynamic configuration file are treated as errors.
+
+### IngressClass
+
+In `v2.3`, the support of `IngressClass`, which is available since Kubernetes version `1.18`, has been introduced.
+In order to be able to use this new resource the [Kubernetes RBAC](../reference/dynamic-configuration/kubernetes-crd.md#rbac) must be updated.

+## Time Zones
+
+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
+
+Overview
+{: .subtitle}
+
+Traefik Pilot is a software-as-a-service (SaaS) platform that connects to Traefik to extend its capabilities.
+It does this through *plugins*, which are dynamically loaded components that enable new features.
+
+For example, Traefik plugins can add features to modify requests or headers, issue redirects, add authentication, and so on, providing similar functionality to Traefik [middlewares](https://docs.traefik.io/middlewares/overview/).
+
+Traefik Pilot can also monitor connected Traefik instances and issue alerts when one is not responding, or when it is subject to security vulnerabilities.
+
+!!! note "Availability"
+    Plugins are available for Traefik v2.3.0-rc1 and later.
+    
+!!! danger "Experimental Features"
+    Plugins can potentially modify the behavior of Traefik in unforeseen ways.
+    Exercise caution when adding new plugins to production Traefik instances.
+
+## Connecting to Traefik Pilot
+
+Plugins are available when a Traefik instance is connected to Traefik Pilot.
+
+To register a new instance and begin working with plugins, login or create an account at the [Traefik Pilot homepage](https://pilot.traefik.io) and choose **Register New Instance**.
+
+To complete the connection, Traefik Pilot will issue a token that must be added to your Traefik static configuration by following the instructions provided.
+
+!!! note "Enabling Alerts" 
+    Health and security alerts for registered Traefik instances can be enabled from the Preferences in your [Traefik Pilot Profile](https://pilot.traefik.io/profile).
+
+## Creating Plugins
+
+Traefik users can create their own plugins and contribute them to the Traefik Pilot catalog to share them with the community.
+
+Plugins are written in [Go](https://golang.org/) and their code is executed by an [embedded Go interpreter](https://github.com/containous/yaegi).
+There is no need to compile binaries and all plugins are 100% cross-platform.
+
+To learn more and see code for example Traefik plugins, please see the [developer documentation](https://github.com/containous/plugindemo).

+# Using Plugins
+
+Plugins are available to any instance of Traefik v2.3 or later that is [registered](overview.md#connecting-to-traefik-pilot) with Traefik Pilot.
+Plugins are hosted on GitHub, but you can browse plugins to add to your registered Traefik instances from the Traefik Pilot UI.
+
+!!! danger "Experimental Features"
+    Plugins can potentially modify the behavior of Traefik in unforeseen ways.
+    Exercise caution when adding new plugins to production Traefik instances.
+
+## Add a Plugin
+
+To add a new plugin to a Traefik instance, you must modify that instance's static configuration.
+The code to be added is provided by the Traefik Pilot UI when you choose **Install the Plugin**.
+
+In the example below, we add the [`blockpath`](http://github.com/containous/plugin-blockpath) and [`rewritebody`](https://github.com/containous/plugin-rewritebody) plugins:
+
+```toml tab="File (TOML)"
+[entryPoints]

+    address = ":80"
+
+[experimental]
+  [experimental.pilot]
+    token = "xxxxxxxxx"

+    [experimental.plugins.block]
+      modulename = "github.com/containous/plugin-blockpath"
+      version = "v0.1.2"
+    [experimental.plugins.rewrite]
+      modulename = "github.com/containous/plugin-rewritebody"
+      version = "v0.2.0"
+```
+
+```yaml tab="File (YAML)"
+entryPoints:
+  web:
+    address: :80

+  pilot:
+    token: xxxxxxxxx

+      modulename: github.com/containous/plugin-rewritebody
+      version: v0.2.0

+--experimental.plugins.rewrite.version=v0.2.0
+```
+
+## Configuring Plugins
+
+Some plugins will need to be configured by adding a dynamic configuration.
+For the `bodyrewrite` plugin, for example:

 ### Further

 If one wants to know more about the various aspects of the Ingress spec that Traefik supports,
-many examples of Ingresses definitions are located in the tests [data](https://github.com/containous/traefik/tree/v2.2/pkg/provider/kubernetes/ingress/fixtures) of the Traefik repository.
-
-## LetsEncrypt Support with the Ingress Provider
-
-By design, Traefik is a stateless application, meaning that it only derives its configuration from the environment it runs in, without additional configuration.
-For this reason, users can run multiple instances of Traefik at the same time to achieve HA, as is a common pattern in the kubernetes ecosystem.
-
-When using a single instance of Traefik with LetsEncrypt, no issues should be encountered, however this could be a single point of failure.
-Unfortunately, it is not possible to run multiple instances of Traefik 2.0 with LetsEncrypt enabled, because there is no way to ensure that the correct instance of Traefik will receive the challenge request, and subsequent responses.
-Previous versions of Traefik used a [KV store](https://docs.traefik.io/v1.7/configuration/acme/#storage) to attempt to achieve this, but due to sub-optimal performance was dropped as a feature in 2.0.
-
-If you require LetsEncrypt with HA in a kubernetes environment, we recommend using [TraefikEE](https://containo.us/traefikee/) where distributed LetsEncrypt is a supported feature.
-
-If you are wanting to continue to run Traefik Community Edition, LetsEncrypt HA can be achieved by using a Certificate Controller such as [Cert-Manager](https://docs.cert-manager.io/en/latest/index.html).
-When using Cert-Manager to manage certificates, it will create secrets in your namespaces that can be referenced as TLS secrets in your [ingress objects](https://kubernetes.io/docs/concepts/services-networking/ingress/#tls).

+A Story of Labels & Elastic Containers

+Attach labels to your containers and let Traefik do the rest!

+## Routing Configuration

+    - labels are case insensitive.

+
+### General
+
+Traefik creates, for each elastic service, a corresponding [service](../services/index.md) and [router](../routers/index.md).
+
+The Service automatically gets a server per elastic container, and the router gets a default rule attached to it, based on the service name.
+
+### Routers
+
+To update the configuration of the Router automatically attached to the service, add labels starting with `traefik.routers.{name-of-your-choice}.` and followed by the option you want to change.
+
+For example, to change the rule, you could add the label ```traefik.http.routers.my-service.rule=Host(`example.com`)```.

+### Middleware
+
+You can declare pieces of middleware using labels starting with `traefik.http.middlewares.{name-of-your-choice}.`, followed by the middleware type/options.
+
+For example, to declare a middleware [`redirectscheme`](../../middlewares/redirectscheme.md) named `my-redirect`, you'd write `traefik.http.middlewares.my-redirect.redirectscheme.scheme: https`.
+
+More information about available middlewares in the dedicated [middlewares section](../../middlewares/overview.md).
+
+!!! warning "The character `@` is not authorized in the middleware name."
+
+??? example "Declaring and Referencing a Middleware"
+    
+    ```yaml
+    # ...
+    # Declaring a middleware
+    traefik.http.middlewares.my-redirect.redirectscheme.scheme=https
+    # Referencing a middleware
+    traefik.http.routers.my-service.middlewares=my-redirect
+    ```
+
+!!! warning "Conflicts in Declaration"
+
+    If you declare multiple middleware with the same name but with different parameters, the middleware fails to be declared.
+
+### TCP
+
+You can declare TCP Routers and/or Services using labels.
+
+??? example "Declaring TCP Routers and Services"
+
+    ```yaml

+    traefik.tcp.services.my-service.loadbalancer.server.port=4123
+    ```
+
+!!! warning "TCP and HTTP"
+
+    If you declare a TCP Router/Service, it will prevent Traefik from automatically creating an HTTP Router/Service (like it does by default if no TCP Router/Service is defined).
+    You can declare both a TCP Router/Service and an HTTP Router/Service for the same elastic service (but you have to do so manually).
