+## TypeScript Support
+
+The Yoti Node SDK is built with TypeScript-first architecture, providing full type definitions for all exports. The SDK automatically compiles TypeScript source to JavaScript with type declarations included.
+
+### Using with TypeScript
+
+```typescript
+import { YotiClient, IDVClient, DigitalIdentityClient } from 'yoti';
+
+const client = new YotiClient('YOUR_SDK_ID', pemString);
+```
+
+### Type Definitions
+
+Type definitions are automatically included and will be recognized by TypeScript and modern IDEs. All classes, interfaces, and functions are fully typed.
+
+### Building from Source
+
+```bash
+npm run build        # Compile TypeScript to dist/
+npm run build:watch  # Watch mode for development
+npm run clean        # Remove build artifacts
+```
