+
+## Docker Compose
+
+With Docker Compose WireGuard Easy can be updated with a single command:
+
+Replace `$DIR` with the directory where your `docker-compose.yml` is located.
+
+```shell
+cd $DIR
+sudo docker compose -f up -d --pull always
+```
+
+## Docker Run
+
+```shell
+sudo docker stop wg-easy
+sudo docker rm wg-easy
+sudo docker pull ghcr.io/wg-easy/wg-easy
+```
+
+And then run the `docker run -d \ ...` command from [Docker Run][docker-run] again.
+
+[docker-run]: ./docker-run.md
+
+## Podman
+
+To update `wg-easy` (and every container that has auto updates enabled), you can run the following commands:
+
+```shell
+sudo podman auto-update
+```
