+**Keep this file under 100 lines.** Prefer terse descriptions. Don't duplicate what's in README.md or DEVELOPMENT.md.
+
+## Development
+```bash
+export ANDROID_HOME=/home/user/android-sdk
+./gradlew assembleDebug        # Build debug APK
+./gradlew assembleRelease      # Build release/production APK
+./gradlew test                 # Run unit tests (JUnit 5)
+```
+Debug APK: `app/build/outputs/apk/debug/com.simplauncher.apk`
+Release APK: `app/build/outputs/apk/release/com.simplauncher.apk`
+
+## Versioning
+Version tracked in `app/build.gradle.kts`: `versionName` (semver) + `versionCode` (integer).
+- **PATCH** (1.0.x): bug fixes, visual tweaks
+- **MINOR** (1.x.0): new features, settings, UI additions
+- **MAJOR** (x.0.0): breaking changes, major redesigns
+- Increment `versionCode` by 1 on every release regardless of semver bump.
+- Tag every release: `git tag -a v1.0.0 -m "description"` then `git push origin v1.0.0`
+- **IMPORTANT:** After any version bump, remind user to upload the release APK to Gogs releases page at https://gogs.altsol.dev/claude/simplauncher/releases
+
+## Repository
+- Remote: `https://gogs.altsol.dev/claude/simplauncher.git`
+- Branch: `master` only
+- Forked from Unlauncher 2.1.1 (itself a fork of Slim Launcher)
+
+## Architecture
+Single-activity (`MainActivity`), multi-fragment app using Navigation Component. MVVM-lite: fragments observe `DataRepository` via LiveData. Hilt DI throughout.
+
+**Package:** `com.simplauncher` — all source under `app/src/main/java/com/simplauncher/`
+
+## Navigation (nav_graph.xml)
+```
+HomeFragment (start) → OptionsFragment
+  → CustomizeHomeFragment → CustomizeHomeAppsAddAppFragment
+  → CustomizeAppDrawerFragment → CustomizeVisibleAppsFragment
+                                → CustomizeSearchFieldFragment
+                                → CustomizeFoldersFragment → CustomizeFolderDetailFragment
+```
+
+## Data Layer
+Three storage systems (migrating everything to Proto DataStore):
+1. **Proto DataStore (primary):** `core_preferences.proto`, `unlauncher_apps.proto`, `quick_button_preferences.proto`, `app_drawer_folders.proto`
+2. **Room DB (legacy):** `BaseDatabase` with `HomeApp` entity, 9 migrations
+3. **SharedPreferences (legacy):** being migrated away
+
+**DataRepository<T>** wraps DataStore with LiveData observation, sync `get()`, and `updateAsync()`.
+All new data should use Proto DataStore.
+
+## Hilt DI
+- **SingletonComponent:** 4 DataStore instances (incl. AppDrawerFolders), BaseDatabase
+- **ActivityComponent:** CorePreferences repo (@WithActivityLifecycle)
+- **FragmentComponent:** All 4 repos (@WithFragmentLifecycle), FragmentManager, CoroutineScope
+
+## UI Patterns
+- View Binding on all fragments
+- MotionLayout for home→drawer transition (swipe up)
+- Pub-sub: MainActivity (IPublisher) → Fragments (ISubscriber) for back/home events
+- App drawer folders: alignment-aware arrows, animated expand/collapse, auto-collapse on home
+- Folder detail settings: checkbox app selector with 3-dot menu (rename/delete)
+- Home screen: up to 6 apps, 3 quick buttons (call/options/camera), clock, date, search bar
+
+## Themes
+9 themes: system (light/dark), midnight, jupiter, teal, candy, pastel, noon, vlad, groovy.
+
+## Permissions
+`QUERY_ALL_PACKAGES`, `REQUEST_DELETE_PACKAGES`, `EXPAND_STATUS_BAR`, `SET_WALLPAPER`, `SET_ALARM`
+
+## Testing
+JUnit 5 + Kotest assertions + MockK. Coverage excludes generated proto/Hilt classes.
+
+## Conventions
+- Kotlin only
+- New preferences → Proto DataStore (never SharedPreferences or Room)
+- Fragment lifecycle: onCreateView (inflate) → onViewCreated (setup) → onStart (attach pub-sub) → onStop (detach)
+- ProGuard keeps protobuf generated classes
