+
+## Quick Start
+
+1. Copy folder: `cp -r ModeTemplate Mode7YourProject`
+2. Update `package.json` name
+3. Install deps: `cd Mode7YourProject && bun install`
+4. Start backend: `bun run backend/server.ts`
+5. Start frontend: `cd frontend && bun run dev`
+
+## Ports
+
+- Backend runs on PORT from env (orchestrator sets to 3005)
+- Frontend dev server runs on 5173 (proxies API to backend)
+
+## Adding to Orchestrator
+
+Edit `ModeSwitch/backend/orchestrator.ts`:
+
+```typescript
+const MODE_FOLDERS: Record<string, string> = {
+  'Mode6Test': 'Mode6Test',
+  'Mode7YourProject': 'Mode7YourProject',  // Add this
+};
+```
