 ### Building
 
-To build the book, do this:
-
+The most straight-forward way to build and view the book locally is to use the following command:
 ```bash
-$ mdbook build
+$ mdbook serve
 ```
 
-The output will be in the `book` subdirectory. To check it out, open it in
-your web browser.
+This serves the book at http://localhost:3000, and rebuilds it on changes.
+You can now view the book in your web browser. If you make changes to the book's source code, 
+you should only need to refresh your browser to see them.
