+
+## Advanced installation instructions
+
+If you are using Home Assistant Container, Home Assistant Core, or you don't want to use the built-in Matter Server add-on, you will need to run the Matter Server yourself, to which the Matter integration will connect.
+
+### Running Matter Server
+
+This application provides the connection between your Matter network (called Fabric in technical terms) and Home Assistant. The Home Assistant Matter integration connects to this server via a websocket connection. You need to run the Matter Server before you can use the integration.
+
+There are multiple ways to run the server:
+
+**Option 1: The official Matter Server add-on, as described above**
+
+_This option is only available for Home Assistant OS (the recommended installation type) and Home Assistant Supervised installations._
+
+**Option 2: Run the Matter server yourself**
+
+This option is considered a very advanced setup and only for experienced users. You can find instructions on how to run the Matter Server in the [project repository](https://github.com/home-assistant-libs/python-matter-server).
