 the script will also attempt to create a **git commit after a successful build** if there are source changes to commit.
 
+It will also automatically bump the Android app version in `app/build.gradle.kts` before each build by:
+
+- incrementing `versionCode` by 1
+- incrementing the patch component of `versionName` (for example `0.1.0` → `0.1.1`)
+
 ## Next steps toward full GitHug parity
 
 - Expand the Git sandbox to cover merge, rebase, stash, tags, remotes, reset, revert, cherry-pick, bisect, and more
