You can help the project out in several ways:
Create an issue to suggest answering a frequently asked question
The purpose of this repository is to answer frequent questions that GitHub users have. If you've got a frequently asked question, you can create an issue to mention it to me, suggesting that I answer the question (or answer it yourself, too).
Create an issue to report a problem
If you find an error, typo, or something that sounds confusing or incorrect, let me know.
Create an issue to suggest a general improvement
Suggest improvements from changes to text, new features, and more.
You can send pull requests to fix errors and make minor adjustments yourself, but if you want to answer a question, you'd be better off making the guide on your own repository, book, or website so that you fully own it.
