Hi there. Thanks so much for helping us out with mozilla.org! There are a few things you should know. Most of the things are in the bedrock docs. These docs have a lot of information about how to get your local environment setup for development, as well as how to format your code and commit messages. Following these guidelines will very much increase the chances of a pleasant code-review experience.
If this is your first time contributing, thanks! Also be sure to add your github username to our humans.txt file if you'd like.
