 ## BuildTool.sh
-The project intentionally runs Gradle with daemon disabled (`--no-daemon` and `org.gradle.daemon=false`).
+The project intentionally runs builds through `./BuildTool.sh` so local development and CI use the same build path.
 
-### Options
+### Common commands
 ```bash
 ./BuildTool.sh --setup-only
-./BuildTool.sh --debug
-./BuildTool.sh --release
-./BuildTool.sh --all
+./BuildTool.sh --no-commit --apk-only
+./BuildTool.sh --no-commit --with-aab
 ```
 
 ### Behavior
-- `--setup-only`: prepares wrapper/dependencies without building release artifacts.
-- `--debug`: increments version code/name, builds debug APK, renames output to include app name and version code.
-- `--release`: increments version code/name, builds release AAB, renames output similarly.
-- `--all`: runs debug + release flow in one run.
-- After successful build tasks, script commits all changes with message from `commit-message.txt` (fallback: `No Details`) and then clears that file.
+- `--setup-only`: prepares the local Android SDK/tooling and exits.
+- `--apk-only`: builds the debug APK.
+- `--with-aab`: also builds the release AAB.
+- `--no-commit`: skips the post-build git commit step.
+- Local builds increment `versionCode` and `versionName`.
+- CI can provide `CI_VERSION_CODE` to force the build version code and `CI_ARTIFACT_TIMESTAMP` to control the release AAB filename.
+- Artifacts are copied into `dist/`.
+- Gitea Actions uses this same script instead of duplicating build logic in YAML.
 
 ## Upload Key (Release Signing)
 For this first increment, release uses default debug signing unless custom signing is added.
