 # Dynamic Web TWAIN with Annotations – Hello World
 
-The Dynamic Web TWAIN library (DWT) is a software development kit (SDK) specifically designed to integrate efficient document scanning workflows into various web applications. The Dynamsoft Document Viewer (DDV) is a versatile web document viewer with support for document annotations. In this guide, we explain how to use DDV in place of the built-in DWT viewer to enable annotations and provide a superior viewer experience.
+Dynamsoft's **Dynamic Web TWAIN (DWT)** is a software development kit (SDK) designed to integrate efficient document scanning workflows into web applications. **Dynamsoft Document Viewer (DDV)** is a versatile web document viewer with support for document annotations. In this guide, we explain how to **use DDV in place of DWT's built-in viewer** to enable **annotations** and provide a superior viewer experience.
+
+In this sample, we create a **headless** DWT instance to scan images, and then pass the result to DDV to view, edit, annotate, etc. We then use DWT to save the result - **along with any edits and annotations** - to a file, or upload to the server.
