Firstly, if you are unsure or afraid of anything, just ask or submit the issue or pull request anyways. You won't be yelled at for giving your best effort. The worst that can happen is that you'll be politely asked to change something. We appreciate any sort of contributions and don't want a wall of rules to get in the way of that.
However, for those individuals who want a bit more guidance on the best way to contribute to the project, read on. This document will cover all the points we're looking for in your contributions, raising your chances of quickly merging or addressing your contributions.
If you come across any bugs or have any future ideas, features you like to suggest, then please do open an issue with the necessary information of the use-case or details on how to reproduce the bug.
Head over to issues to find issues where help is needed from contributors.
Provide PR's with all necessary information about the issue(s) you are fixing in the pull request or the feature/enhancement you are trying to add. Also, demonstrate the change through screenshots, or live demos if possible.
We look forward to all your contributions.
