 ## Deploying
 
-Releases are built by Gitea Actions. Pushing a tag such as `v0.2.0` runs `.gitea/workflows/release.yml`, which tests the code, builds Hammerhead for Linux (amd64, arm64, armv7), Windows (amd64) and macOS (amd64, arm64), publishes the archives with a `SHA256SUMS` file on the Releases page, and pushes a multi-architecture container image to this server's registry (`git.veillax.com/veillax/hammerhead`). Every push and pull request runs `.gitea/workflows/ci.yml`: formatting, vet, tests, and a check that every release platform still compiles.

To upgrade, repeat the same steps: your settings and data are kept. `sudo ./install.sh --uninstall` removes the service and binary but leaves `/etc/hammerhead` and `/var/lib/hammerhead` alone. `hammerhead -version` tells you which build is running.
