 ## Core Concepts
 
+**The Mayor** is your AI coordinator. It's Claude Code with full context about your workspace, projects, and agents. The Mayor session (`gt prime`) is the primary way to interact with Gas Town - just tell it what you want to accomplish.

 **Hook**: Each agent has a hook where work hangs. On wake, run what's on your hook.

 ## Workflows
 
+### Full Stack (Recommended)
+
+The primary Gas Town experience. Agents run in tmux sessions with the Mayor as your interface.
+
+```bash
+gt start                               # Start Gas Town (daemon + Mayor session)
+cd ~/gt && gt prime                    # Enter Mayor session
+
+# Inside Mayor session, just ask:
+# "Create a convoy for issues 123 and 456 in myproject"
+# "What's the status of my work?"
+# "Show me what the witness is doing"
+
+# Or use CLI commands:
+gt convoy create "Feature X" issue-123 issue-456
+gt sling issue-123 myproject           # Spawns polecat automatically
+gt convoy list                         # Dashboard view
+gt agents                              # Navigate between sessions
+```

 ### Minimal (No Tmux)
 
 Run individual Claude Code instances manually. Gas Town just tracks state.
