Git lab
Version control by doing. Learn mode covers committing, branching and merging, undoing, and reading history; Break-fix mode rescues a repository from detached HEAD, conflicts, and worse.
Why this matters: Git is the one tool you touch every single day, and the one most people only half-know. The gap shows up under pressure — mid-conflict, mid-rebase, with a broken main branch and an audience.
