Currently their are no standards for contributing. Once the project gets big enough we can add it later. If you want to contribute you can send in a pull request. If you want something new to be added you can put it in as an issue like what others have done.
If you have any issues or if I have not seen your issue / pull request in a few days then feel free to send an email to ccmonks32@gmail.com
Thanks for contributing / adding in issues / using this library.
