+The header shows the running version and, behind it, the build stamp (the newest
+source file, or `WORDARR_BUILD` when the image was built with it) - the quickest
+way to see whether a redeploy actually arrived. `GET /api/version` returns the
+same three values. Build with the git sha via
+`WORDARR_BUILD=$(git rev-parse --short HEAD) docker compose up -d --build`.

+The UI speaks German and English; the button next to the navigation switches
+between them and remembers the choice. Without one, the browser language decides.

+## Build
+
+`.gitea/workflows/build.yml` runs the tests on every push to `main` and then
+builds and pushes `gitea.steppencloud.de/admin/wordarr` as `:latest` and
+`:<short sha>`, passing that sha as `WORDARR_BUILD`. It logs in with
+`REGISTRY_TOKEN` if the secret exists, otherwise with the runner's own
+`GITEA_TOKEN`. The last step pulls the fresh image on the host and recreates
+just the wordarr container of the arr stack, so the version in the header is the
+commit that was pushed.
