+#### Git worktrees
+
+`<leader>gw` opens a Telescope picker of **every branch** in the current project
+(local + remote) and shows at a glance which ones are checked out on this
+machine: the current branch is bold, branches with a worktree are highlighted
+green with their path, and remote-only branches are dimmed with a globe icon.
+
+- `<CR>` **switch** — jumps to the branch's worktree, creating it on demand.
+  Remote-only branches are pulled down as tracking local branches first.
+- `<c-f>` **fetch remotes** — runs `git fetch --all --prune` so new remote
+  branches (e.g. `renovate/*`) appear in the list, then refreshes.
+- `<c-d>` **remove** — deletes the selected worktree (or local-only branch).
+- `<c-n>` **new** — prompts for a branch name (+ base) and creates its worktree.
+- `<c-r>` **refresh** — re-reads local/remote state.
+
+`:GitWorktreeConvert` (or `<leader>gC`) turns a plain single-checkout repo into
+a worktree layout without losing anything: every local branch gets its own
+linked worktree under `<parent>/.worktrees/<project>/<branch>` (main keeps its
+place), so all branches that were on the machine stay available. Pass
+`--keep=<branch>` to choose which branch remains at the main worktree.
+
+The snacks explorer (`<C-e>`) shows a chip in its title with the current
+project, branch, and worktree count when inside a git repo.
