+# TestFlight Release CI
+
+Gitea Actions publishes iOS releases from tags that match:
+
+```sh
+release/vN.N.N
+```
+
+For example:
+
+```sh
+git tag release/v1.10.0
+git push origin release/v1.10.0
+```
+
+The release job runs on the `xcode` runner label, imports the signing p12 with
+`Apple-Actions/import-codesign-certs`, builds and uploads the app with fastlane,
+then creates or updates the matching Gitea release with the generated IPA as an
+asset.
+
+Required repository secrets:
+
+```text
+APPSTORE_CERTIFICATES_FILE_BASE64
+APPSTORE_CERTIFICATES_PASSWORD
+FASTLANE_USER
+FASTLANE_APPLE_APPLICATION_SPECIFIC_PASSWORD
+```
+
+The workflow uses Gitea's built-in `GITEA_TOKEN` for release creation and asset
+upload, with `contents: write` permissions. In Gitea this covers release asset
+publication.
