+## What it is
+
+Git records the history of a project's files. Each commit is a snapshot you can go back to, compare or undo, and branches let you work on several changes at once and merge them when they're ready. It's distributed: every copy of a repository has the full history, and you share work by pushing and pulling between copies, often through GitHub, GitLab or Gitea.
+
+## Why it's here
+
+- **The standard.** Nearly every open-source and commercial project uses it.
+- **Safe experiments.** Branch, try something, and throw it away if it doesn't work.
+- **Needed by everything else.** Editors, AI agents and installers all use Git.
+
+## On CoreDesktop
+
+Git is installed from pacman. CoreDesktop adds shell shortcuts for it:
+
+- `g` for `git`, and `lg` for [lazygit](/software/lazygit/)
+- `gcm "message"` commits with a message, `gcam "message"` commits all changed files, and `gcad` adds changed files to the last commit
+- `ga <branch>` creates a worktree for a new branch next to the current repository, in `../<repo>--<branch>`, and moves you into it; `gd`, run inside it, removes the worktree and its branch
+
+`update` keeps Git current with the rest of the pacman packages.
