+# Worktrunk Setup
+
+This repo uses [Worktrunk](https://github.com/max-sixty/worktrunk) for running multiple Claude Code agents in parallel on different branches.
+
+## Install Worktrunk
+
+```bash
+brew install max-sixty/worktrunk/wt
+wt config shell install
+# restart terminal
+```
+
+## Quick Commands
+
+| Task | Command |
+|------|---------|
+| Create worktree + start Claude | `wt switch -c -x claude feat-name` |
+| Switch to existing worktree | `wt switch feat-name` |
+| List all worktrees | `wt list` |
+| Create PR | `gh pr create` |
+| Remove worktree | `wt remove feat-name` |
+
+## What happens on `wt switch -c`
+
+1. Creates new worktree at `../browseros-main.feat-name/`
+2. Runs `bun install` in `packages/browseros-agent/`
+3. Copies `.env.*` files from main worktree's `packages/browseros-agent/apps/`
+
+## Hooks
+
+Hooks are configured in `.config/wt.toml`:
+
+- **post-create**: Runs `bun install` in the agent package, copies env files and `.llm/` from the main worktree
+- **pre-remove**: Syncs `.llm/` back to the main worktree before deletion
