+<h1>Anchor Scrolling</h1>
+
+> Author: Thomas Laforge
+
+### Information
+
+You begin with an application that has basic navigation and anchor navigation in the `HomeComponent`. However, using `href` recreates the path each time and refreshes the page.
+
+### Statement
+
+- Your task is to refactor this application to use the built-in navigation tool to better fit within the Angular Framework. You can explore the router, but it's better to stay within the template and use the `RouterLink` directive.
+- To improve the user experience, add smooth scrolling.
+
+### Submitting your work
+
+1. Fork the project
+2. clone it
+3. npm install
+4. `npx nx serve anchor-scrolling`
+5. _...work on it_
+6. Commit your work
+7. Submit a PR with a title beginning with **Answer:21** that I will review and other dev can review.
