+## Automatic deployment
+
+Gitea Actions tests and publishes the website after every push to `main`. The
+workflow in [`.gitea/workflows/deploy.yml`](.gitea/workflows/deploy.yml) syncs
+the contents of `web/` to
+`firewallissues-deploy@<DEPLOY_HOST>:/var/www/html/firewallissues/web/`.
+It can also be run manually from the Actions page.
+
+Before the first deployment:
+
+1. Enable Actions for the Gitea repository and make sure an `ubuntu-latest`
+   runner is available.
+2. Create a dedicated `firewallissues-deploy` account and SSH key pair. Install
+   the public key for that account and give it ownership of
+   `/var/www/html/firewallissues/web/`.
+3. Add these repository Actions secrets in Gitea:
+
+   - `DEPLOY_HOST`: the web server hostname or IP address as reached by the
+     Actions runner.
+   - `DEPLOY_SSH_KEY`: the complete private key, including its BEGIN and END
+     lines.
+   - `DEPLOY_KNOWN_HOSTS`: the web server's trusted SSH host-key line. Generate
+     it from a trusted network with `ssh-keyscan -H <DEPLOY_HOST>`, then verify
+     its fingerprint before saving it.
+
+The deploy account only needs write access to the site's `web` directory.
