+## Connecting services
+
+Add the `proxy.network` to the service you would like to proxy. This can be done by either editing the quadlet directly or creating a systemd override like so:
+
+1. Create a folder next to the container/pod file: `$name.$type.d/` (e.g. `nginx.container.d/`)
+2. Create a config file (e.g. `proxy.conf`) in this folder with the following contents:
+```yaml
+[Container]
+Network=proxy.network
+```
+
+> [!TIP]
+> The config is also available to copy under `assets/proxy-network.conf`!
