+- `ci` - CI configuration changes
+
+### Release Process
+
+1. Make commits using conventional commit format
+2. Push to `main` branch
+3. Release-please automatically creates/updates a release PR
+4. Review and merge the release PR
+5. GitHub Action builds and uploads binaries to the release
+
+### Manual Version Sync
+
+Version is defined in three places that release-please keeps in sync:
+- `package.json` - `version` field
+- `src-tauri/Cargo.toml` - `version` field
+- `src-tauri/tauri.conf.json` - `version` field
+
