### Alternative: Install via CLI

If you use Cursor, Claude Code, or any MCP-compatible AI tool, you can install Summer Engine from the command line:

```bash theme={null}
npx -y summer-engine@latest install
```

This downloads and installs Summer Engine (macOS: `/Applications/Summer.app`; Windows:
the installer-selected location). No global npm install is required. After installation:

```bash theme={null}
npx -y summer-engine@latest login
npx -y summer-engine@latest run
```

For MCP setup (connecting your IDE to Summer Engine), see [MCP Setup](/mcp/setup).
