Contributions to the VVV project are more than welcome.
By contributing code to the VVV project and other sub-projects, you agree to license your contribution under the MIT License.
Issues should be opened on the main VVV repository. Open a GitHub issue for anything. We've covered quite a bit of ground over time, so it would be helpful to search for related topics first. That said, don't worry if you find yourself opening something that sounds like it could be obvious. There is no such thing.
Comment on any GitHub issue, open or closed. The only guidelines here are to be friendly and welcoming. If you see that a question has been asked and you think you know the answer, don't wait!
Pull Requests for VVV extensions can be submitted to this repository. Please consider opening an issue on the VVV repository first so that we can discuss goals and approach. If you feel more comfortable showing intent with code, then opening a pull request at the same time is more than welcome.
