First off, thank you for considering contributing to MonoAGS. Every contribution is very appreciated.
If you want to submit a small bug fix, or feature, fork the repository's master branch, make your changes in your fork and then submit a pull request. If you want to work on a big feature/refactoring, please open an issue first so that we can start a discussion. Before opening an issue, check if an issue already exists, and if it does, then respond on that issue and say you want to work on it so we can discuss. This is mainly to ensure you don't do hard work for no reason, as we may already have conflicting plans.
You can create issues for bugs, feature requests or general questions. Please search first to see if a similar issue was already created.
Please vote on issues that are important to you (thumbs up the first comment of the issue). This gives us a clue about what feature/fix is most desired.
