+## Dashboard
 
+You need to activate the [API](../operations/dashboard.md#enabling-the-dashboard) to access the dashboard.
+As the dashboard access is now secured by default you can either:
+
+* define a  [specific router](../operations/api.md#configuration) with the `api@internal` service and one authentication middleware like the following example
+* or use the [unsecure](../operations/api.md#insecure) option of the API
+
+!!! note "Dashboard with k8s and dedicated router"
+
+    As `api@internal` is not a Kubernetes service, you have to use the file provider or the `insecure` API option.

+## Some Tips You Should Known
+
+* Different sources of static configuration (file, CLI flags, ...) cannot be [mixed](../getting-started/configuration-overview.md#the-static-configuration).
+* Now, configuration elements can be referenced between different providers by using the provider namespace notation: `@<provider>`.
+  For instance, a router named `myrouter` in a File Provider can refer to a service named `myservice` defined in Docker Provider with the following notation: `myservice@docker`.
+* Middlewares are applied in the same order as their declaration in router.
+* If you have any questions feel free to join our [community forum](https://community.containo.us).
