## ✅ Completed Documentation Components

### 1. **Inline Code Documentation**
All source code files now include comprehensive Google-style documentation:

- **`src/main.rs`** - Complete module overview, function documentation with examples
- **`src/config.rs`** - Configuration system docs with usage patterns  
- **`src/llm_provider.rs`** - LLM provider interface and implementation docs
- **`src/ui.rs`** - Extensive UI component documentation with ASCII layouts

### 2. **User Documentation**
Created in `/docs/` directory:

- **`user_guide.md`** - Complete user manual with ASCII art and examples
- **`developer_guide.md`** - Technical guide for contributors and developers
- **`README.md`** - Documentation generation and maintenance guide
- **`index.md`** - Central documentation index with navigation

### 3. **API Documentation** 
Detailed API docs in `/docs/api/`:

- **`main.md`** - Core application flow and entry points
- **`config.md`** - Configuration management API
- **`llm_provider.md`** - LLM provider interface
- **`ui.md`** - User interface components and interactions

### 4. **Documentation Infrastructure**

- **VS Code Task**: `Generate Documentation` for one-click doc generation
- **`.gitignore`**: Excludes generated docs from version control
- **Rustdoc Integration**: Configured for HTML output with proper linking
