+# Repository Guidelines
+
+This monorepo hosts Rollbar SDKs for Dart and Flutter. Use the package-level READMEs for usage examples, and follow the guidelines below when contributing.
+
+## Project Structure & Module Organization
+
+- `rollbar_common/`: shared Dart core (models, serialization, extensions) used by both SDKs; tests live in `rollbar_common/test`.
+- `rollbar_dart/`: pure Dart notifier package with examples in `rollbar_dart/example` and tests in `rollbar_dart/test`.
+- `rollbar_flutter/`: Flutter plugin and platform integration; Dart sources in `rollbar_flutter/lib`, native code in `rollbar_flutter/android` and `rollbar_flutter/ios`, tests in `rollbar_flutter/test`, and a sample app in `rollbar_flutter/example`.
+- `build_tools/`: scripts for linting, tests, builds, and publishing.
+
+## Build, Test, and Development Commands
+
+- `./build_tools/check.sh`: runs the standard CI-style pipeline across packages (pub get, `flutter test`, `flutter analyze`, `pana`, Gradle checks, and example builds).
+- `./build_tools/build.sh -d rollbar_dart test`: run a single task in one package (tasks include `pub-get`, `test`, `analyze`, `pana`, `gradle-check`, `example-android`, `example-ios`).
+- `./build_tools/clean.sh`: `flutter clean` for all packages.
+- `cd rollbar_flutter/example && flutter run`: run the Flutter example app locally.
+
+## Coding Style & Naming Conventions
+
+- Dart code follows standard formatting (2-space indent) and analyzer rules from `analysis_options.yaml` in each package.
+- Lints include `prefer_single_quotes`, `always_declare_return_types`, and `unawaited_futures` (plus `sort_child_properties_last` in `rollbar_dart`).
+- Use Dart naming conventions: `UpperCamelCase` for types, `lowerCamelCase` for members, `snake_case` for files.
+
+## Testing Guidelines
+
+- Tests are organized under each package’s `test/` directory and run via `flutter test` from that package root.
+- Android unit tests live under `rollbar_flutter/android/src/test`.
+- Add or update tests for new behavior; there is no explicit coverage gate, but regression tests are expected.
+
+## Commit & Pull Request Guidelines
+
+- Commit messages are short and imperative; optional type/scope prefixes are common (e.g., `feat: ...`, `fix(android): ...`, `doc: ...`).
+- Before opening a PR, run `./build_tools/check.sh` and note results in the PR description.
+- Link relevant issues and describe platform-specific changes (Dart vs. Flutter, Android vs. iOS) clearly.
+
+## Security & Configuration Tips
+
+- Never commit real Rollbar access tokens; use placeholders like `YOUR-ROLLBAR-ACCESSTOKEN` in examples and tests.
