+# Release process
+
+## 1. Create RC branch
+
+```bash
+git checkout main
+git pull origin main
+git checkout -b rc-minor-fleetd-android-v1.X.X
+```
+
+## 2. Update version numbers
+
+In `app/build.gradle.kts`, update:
+
+```kotlin
+defaultConfig {
+    versionCode = 2          // Increment by 1 each release
+    versionName = "1.1.0"    // Semantic version for display
+}
+```
+
+- `versionCode`: Integer that must increase with each release (Google Play requirement)
+- `versionName`: Human-readable version string shown to users
+
+## 3. Update CHANGELOG.md
+
+Add an entry for the new version with changes since the last release.
+
+## 4. Commit and push RC branch
+
+```bash
+git add app/build.gradle.kts CHANGELOG.md
+git commit -m "Prepare release v1.1.0"
+git push origin rc-minor-fleetd-android-v1.X.X
+```
+
+## 5. Test the RC
+
+- Build and test the release candidate
+- Fix any issues on the RC branch (cherry-pick fixes from main if applicable)
+
+## 6. Build signed release
+
+Ensure `keystore.properties` is configured with the release signing key.
+
+```bash
+./gradlew clean bundleRelease
+```
+
+Output: `app/build/outputs/bundle/release/app-release.aab`
+
+## 7. Upload to Google Play
+
+1. Go to [Google Play Console](https://play.google.com/console)
+2. Select the Fleet app
+3. Navigate to Release > Production (or appropriate track)
+4. Upload the signed AAB
+5. Add release notes
+6. Review and roll out
+
+## 8. Tag the release
+
+After the release is uploaded, tag the RC branch:
+
+```bash
+git checkout rc-minor-android-v1.X.X
+git tag fleetd-android-v1.X.X
+git push origin rc-minor-fleetd-android-v1.X.X
+```
+
+## 9. Bring version bump and CHANGELOG to main
+
+```bash
+git checkout main
+git checkout rc-minor-fleetd-android-v1.X.X -- app/build.gradle.kts CHANGELOG.md
+git commit -m "Update version and CHANGELOG for fleetd-android-v1.X.X"
+git push origin main
+```
+
+This brings only the version bump and CHANGELOG updates to main, not other RC changes.
