## Quick Start

### 1. Install and run

```bash
pipx install cognix
cognix
```

### 2. First-time setup

When you run Cognix for the first time, an interactive wizard will help you set up your API key:

- Choose your AI provider (Anthropic, OpenAI, or OpenRouter)
- Enter your API key
- The wizard creates a `~/.cognix/.env` file automatically

### 3. Generate code

Try the included sample first (use `@` to specify a file):

```bash
cognix> /make @sample_spec_tetris.md
```

Or describe what you want to build:

```bash
cognix> /make "landing page with HTML and CSS"
```

A sample specification file `sample_spec_tetris.md` is included in the repository. Use it as a reference for writing your own specifications.

### 4. Available commands

Type `/help` in the CLI to see all available commands.

      "command": "cognix-mcp"
    }
  }
}
```
