 # Gurty - a CLI tool to setup your GURT Protocol server
 
+Gurty is a command-line interface tool for setting up and managing GURT protocol servers.
+
+## Configuration
+
+Gurty uses a TOML configuration file to manage server settings. The `gurty.template.toml` file provides a complete configuration template with all available options:
+
+### Sections
+
+- **Server**: Basic server settings (host, port, protocol version, connection limits)
+- **TLS**: Certificate and private key configuration for secure connections
+- **Logging**: Logging levels, request/response logging, and log file paths
+- **Security**: File access restrictions, allowed HTTP methods, and rate limiting
+- **Error Pages**: Custom error page templates and default error responses
+- **Headers**: Custom HTTP headers for security and server identification
+
+### Using Configuration Files
+
+1. **Copy the configuration template:**
+   ```bash
+   cp gurty.template.toml gurty.toml
+   ```
+
+2. **Edit the configuration** to match your environment. (optional)
+
+3. **Use the configuration file:**
+   ```bash
+   gurty serve --config gurty.toml
+   ```
+
