+# Contributing
+
+Thank you so much for your interest in contributing! All types of contributions are encouraged and valued. The Project Team looks forward to your contributions.
+
+## Filing Issues
+
+When in doubt, file an issue. We'd rather close a few duplicate issues than let a problem go unnoticed. Similarly, if you support a particular feature request, please let us know by commenting on the issue or [subscribing](https://help.github.com/articles/subscribing-to-conversations/) to the issue.
+
+If you are reporting a bug, please help speed up problem diagnosis by providing as much information as possible. Ideally, that would include a small sample project (or gist) that reproduces the problem.
+
+## Contributing Code
+
+We actively welcome your pull requests. You can find instructions on building the project in [README.md](https://github.com/canopas/group-track-flutter).
+
+1. Fork the repo and create your branch from `main`.
+2. If you've added code that should be tested, add tests.
+3. Make sure your code lints.
+
+## Labels
+
+Labels on issues are managed by contributors; you don't have to worry about them. Here's a list of what they mean:
+
+- **bug**: Feature that should work, but doesn't.
+- **enhancement**: Minor tweak/addition to existing behavior.
+- **feature**: New behavior, bigger than enhancement.
+- **question**: No need for any fix, usually a usage problem.
+- **reproducible**: Has enough information to very easily reproduce, mostly in the form of a small project in a GitHub repo.
+- **repro-needed**: We need some code to be able to reproduce and debug locally; otherwise, there's not much we can do.
+- **duplicate**: There's another issue that already covers/tracks this.
+- **wontfix**: Working as intended, or won't be fixed due to compatibility or other reasons.
+- **invalid**: There isn't enough information to make a verdict, or unrelated.
+- **non-library**: Issue is not in the core library code, but rather in documentation, samples, build process, or releases.
