+# Contributing to React Native Bundle Visualizer
+
+Thank you for helping out with **react-native-bundle-visualizer**. We'd like to make contributions as
+pleasant as possible, so here's a small guide of how we see it. Happy to hear your feedback about anything, so please let us know.
+
+## Tests
+
+All tests are run on Github Actions on opening a pull request or pushing to main, but you should use them locally when making changes.
+
+- `yarn test`: Run tests for react native cli app and expo app.
+- `yarn test:rn`: Run tests only for react native cli app.
+- `yarn test:expo`: Run tests only for expo app.
+
+## Sending a pull request
+
+When you're sending a pull request:
+
+- If you want fix/add something, please open new/ find existing issue, so we can discuss it.
+- We prefer small pull requests focused on one change, as those are easier to test/ review.
+- Please make sure that all tests are passing on your local machine.
+- Follow the template when opening a PR.
+
+## Commits and versioning
+
+All PRs are squashed into `master` branch and wrapped up in a single commit,
+following [conventional commit message](https://www.conventionalcommits.org/en/v1.0.0-beta.3).
+
+Most notably prefixes you'll see:
+
+- **fix**: Bug fixes, triggers _patch_ release
+- **feat**: New feature implemented, triggers _minor_
+- **chore**: Changes that are not affecting end user (CI config changes,
+  scripts, ["grunt work"](https://stackoverflow.com/a/26944812/3510245))
+- **docs**: Documentation changes.
+- **perf**: A code change that improves performance.
+- **refactor**: A code change that neither fixes a bug nor adds a feature.
+- **test**: Adding missing tests or correcting existing tests.
+
+## License
+
+By contributing to React Native Bundle Visualizer, you agree that your contributions
+will be licensed under the **MIT** license.
