+## Reverse Proxy Config
+
+Basically, you need to specify the port that the apache container shall use and modify the startup command a bit.
+
+All examples below will use port `11000` as example apache port. Also it is supposed that the reverse proxy runs on the same server like AIO, hence `localhost` is used and not an internal ip-address to point to the AIO instance. Modify both to your needings.
+
+### Caddy reverse proxy config example
+
+Add this to your Caddyfile:
+
+```
+https://<your-nc-domain>:443 {
+    header Strict-Transport-Security max-age=31536000;
+    reverse_proxy localhost:11000
+}
+```
+
+Of course you need to modify `<your-nc-domain>` to the domain on which you want to run Nextcloud.
+
+### Startup command
+
+```
+# For x64 CPUs:
+sudo docker run -it \
+--name nextcloud-aio-mastercontainer \
+--restart always \
+-p 8080:8080 \
+-e APACHE_PORT=11000 \
+--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
+--volume /var/run/docker.sock:/var/run/docker.sock:ro \
+nextcloud/all-in-one:latest
+```
+
+<details>
+
+<summary>Command for arm64 CPUs like the Raspberry Pi 4</summary>
+
+```
+# For arm64 CPUs:
+sudo docker run -it \
+--name nextcloud-aio-mastercontainer \
+--restart always \
+-p 8080:8080 \
+-e APACHE_PORT=11000 \
+--volume nextcloud_aio_mastercontainer:/mnt/docker-aio-config \
+--volume /var/run/docker.sock:/var/run/docker.sock:ro \
+nextcloud/all-in-one:latest-arm64
+```
+
+</details>
+
+After doing so, you should be able to access the AIO Interface via `https://internal.ip.of.this.server:8080`. Enter your domain that you've entered in the reverse proxy config and you should be done. Please do not forget to open port `3478/TCP` and `3478/UDP` for the Talk container!
+
+### Optional
+
+If you want to also access your AIO interface publicly with a valid certificate, you can add e.g. the following config to your Caddyfile:
+
+```
+https://<your-nc-domain>:8443 {
+    reverse_proxy https://localhost:8080 {
+        transport http {
+            tls_insecure_skip_verify
+        }
+    }
+}
+```
+
+Of course you also need to modify `<your-nc-domain>` to the domain that you want to use. Afterwards should the AIO interface be accessible via `https://<your-nc-domain>:8443`.
