 9. Serve the build locally. For example using VS Code, click on `_build/html/index.html` and click Open with Live Server which should launch a local build of the website and should reload within a few seconds each time you save a `.md` or `.yml` file in VS Code (you may need to refresh the page once Run on Save is done each time). You may need to navigate to the proper URL such as http://localhost:5500/\_build/html/.
