+## Configure
+On first run, simply using `MATRIX_DOMAIN` as an environment variable will create a default config for you.  
+You can also provide a configuration file named `mxisd.yaml` in the volume mapped to `/etc/mxisd` before starting your
+container.
+
 ## Run
-Run it (adapt volume paths to your host):
+Use the following command after adapting to your needs:
+- The `MATRIX_DOMAIN` environment variable to yours
+- The volumes host paths
