Git Worktrees Tutorial #1 - What are Git Worktrees?

Git worktrees are working directories linked to the same repository, allowing developers to check out multiple branches simultaneously without stashing or making premature commits. Unlike cloning a repo multiple times, worktrees share the same git history, remotes, and commits, so a single fetch updates everything. Git also prevents checking out the same branch in two worktrees at once. This introductory video explains the concept and the problem worktrees solve when needing to switch context mid-feature, with a follow-up planned on their use in agentic coding workflows.
