   ```

3. **Verify installation**:
   ```bash
   claude-flow --version  # Should show 2.0.0
   claude-flow --help     # Verify all commands available
   ```

### Configuration Updates

1. **Initialize new features**:
   ```bash
   npx claude-flow init --sparc
   ```

2. **Test swarm capabilities**:
   ```bash
   npx claude-flow swarm init
