Git worktree basics
Worktrees allow multiple working directories attached to a single repository. I think of a worktree as a sort of checked out instance of a repo.
Instead of having multiple folders of the same repo checked out on your disk, you could use worktrees for the same benefits. There's more seperation than with branches.
To create a new worktree from an existing branch:git worktree add <branch>
You will need to supply a name for the worktree or if you pass it a branch name it will create a worktree checked out to the branch passed it named after the branch.
Worktrees are created relative to the the current directory, so if you want to create a worktree at the same level as your current directory (which you probably do) you should prefix your name with ../ .
To list worktrees:git worktree list
And, to remove them:git worktree remove <worktree name>
The slightly counterintuitive bit is checking out to a worktree. Each worktree is its own directory, so to 'check it out' you use cd.
