 The `docker-compose.yml` file statically references the latest version available at the time of downloading the compose file. Each time you upgrade to a newer version of authentik, you download a new `docker-compose.yml` file, which points to the latest available version. For more information, refer to the **Upgrading** section in the [Release Notes](../releases).
 
-By default, authentik is reachable (by default) on port 9000 (HTTP) and port 9443 (HTTPS).

+## Explanation
+
+:::warning
+The server assumes to have local timezone as UTC.
+All internals are handled in UTC; whenever a time is displayed to the user in UI it gets localized.
+Do not update or mount `/etc/timezone` or `/etc/localtime` in the authentik containers.
+This will not give any advantages.
+On the contrary, it will cause problems with OAuth and SAML authentication,
+e.g. [see this GitHub issue](https://github.com/goauthentik/authentik/issues/3005).
+:::
+
+The Docker-Compose project contains the following containers:
+
+-   **Server**: This is the backend service, which does all the logic, plus runs the API and the SSO functionality. It also runs the frontend, hosts the JS/CSS files, and serves the files you've uploaded for icons/etc.
+
+-   **Worker**: This container executes background tasks, everything you can see on the _System Tasks_ page in the frontend.
+
+-   **Redis**: For Cache
+
+-   **Postgresql**: Default database
