 ```
 open _build/html/index.html

+However, many of the links will not work. For all of the links found in the portal to work properly, you'll need to set up a local testing server. This can be done with Python's http.server by running the following command from within the `content` directory:
+
+```
+python -m http.server --directory _build/html/
+```
+
+and then pointing your browser at the URL: `localhost:8000`.
