 - **SSH connections** start from the server, so the server must be able to reach your hosts.

+### Updating the web version
+
+Run these commands in the folder that contains your `docker-compose.yml`:
+
+```bash
+docker compose build --pull --no-cache
+docker compose up -d
+```
+
+This fetches the latest MrTerm from the repository, rebuilds the image and restarts the container. Your users and vaults stay in the `mrterm-data` volume and are kept. Everyone has to sign in again after the restart.
+
+To check which version is running, look at the bottom of the sign-in page. If a release note mentions changes to `docker-compose.yml`, download it again first (`curl -O …` as above) and copy over your own changes, such as ports or `TRUST_PROXY`.
+
+To remove images left over from earlier builds: `docker image prune`.
