Book: Introduction and Practice with GitHub
Git solves version management; GitHub solves collaboration, hosting, presentation, and an entire workflow built around repositories. Many people know git add and git commit, but when it comes to Pull Requests, Issues, Forks, collaboration permissions, and project pages, the platform itself can feel unfamiliar.
This material lives in the Git section as a supplement to the command reference. It focuses more on how to use the GitHub platform, and is worth reading before you start contributing to open source projects, organizing personal projects, or collaborating with others.
