+- Generates configurable number of commit message suggestions from your staged diff
+- Providers: GitHub Copilot (default), OpenAI, Anthropic (Claude Code CLI)
+- Multi-language support: English and Spanish

+#### Anthropic Provider (Claude Code CLI)
+
+The Anthropic provider integrates with your local [Claude Code CLI](https://github.com/anthropics/claude-code) installation:
+
+- **No API key required**: Uses your existing Claude Code authentication
+- **Fast and cost-effective**: Leverages Claude Haiku model
+- **Configurable**: Set custom number of suggestions per provider
+
+Requirements:
+- Claude Code CLI installed and authenticated
+- Command `claude` available in PATH
+
 ### 2. Prompt Configuration (`~/.config/.lazycommit.prompts.yaml`)
 Contains prompt templates and message configurations. **Safe to share in dotfiles and Git.**

+### Language Configuration
+
+lazycommit supports generating commit messages in different languages. Set the `language` field in your config:
+
+```yaml
+language: es  # Spanish
+# or
+language: en  # English (default)
+```
+
+You can also configure it interactively:
+
+```bash
+lazycommit config set  # Select language in the interactive menu
+```
+
+The language setting automatically instructs the AI to generate commit messages in the specified language, regardless of the provider used.
+
+**Supported languages:**
+- `en` - English (default)
+- `es` - Spanish (Español)
+
 ## Integration with TUI Git clients
 
 Because `lazycommit commit` prints plain lines, it plugs nicely into menu UIs.
