+## Versioning
+
+Version is defined in `app/build.gradle.kts` (`versionCode` and `versionName`).
+
+- **Format:** Semantic versioning `MAJOR.MINOR.PATCH` (e.g., `0.2.0`)
+- **`versionCode`:** Integer, increment by 1 on every release (used by Google Play)
+- **`versionName`:** Human-readable, shown in Settings screen
+
+**When to bump:**
+- **PATCH** (0.2.0 → 0.2.1): Bug fixes, small tweaks, no new features
+- **MINOR** (0.2.0 → 0.3.0): New features, UI changes, significant improvements
+- **MAJOR** (0.x → 1.0): First stable public release
+
+**Current:** `versionName = "0.2.0"`, `versionCode = 2`
+
+**Process:** When making a release commit, bump both `versionCode` (+1) and `versionName` in `app/build.gradle.kts`. Always bump version when creating a release build or PR.
