GitHub is a hosted place where repositories live: code, skills, documentation, settings, and a README that explains what each repo is for. It sits on top of git. Git tracks the changes; GitHub hosts the repo, shows those changes in a browser, and gives teams a place to review work before it affects everyone.
Google Drive for code is the closest match. Picture a shared drive built for software: you put project folders in it and give people access, but it also remembers every change and adds a review desk where edits get checked before they become official.
Why you care
GitHub isn’t only for professional developers. If your team shares Claude skills, scripts, or website files, it may be the cleanest home, because agents like Codex and Claude Code already understand its conventions and can read files and propose edits within the permissions you give them. When someone opens a pull request, others review the difference before it ships, so one person’s edit doesn’t quietly become the whole team’s new process. Start with the shared-drive picture, then add the one thing that makes GitHub different: it remembers and reviews changes.
