GitMagic enforces your GitHub contribution guidelines by letting you define how you want your commit messages to look like, what a pull request must include, and how issues should be reported.
Based on these rules, a CONTRIBUTING.md file will be auto-generated so it's easy for your contributors to understand your guidelines. Your guidelines will then be enforced by our bots and build checks. All you would have to do is to sign up using GitHub and activate GitMagic for your repos.
