+ReactJS with Live Reloading
+===========================
+
+If you'd like to take take advantage of ReactJS to develop your UI:
+
+- Start Django server in the project root run:
+
+    $ python manage.py runserver
+
+- Make sure that yarn_ is installed.  Then in a second terminal, run the following in the project root::
+
+    $ cd frontend
+    $ yarn install
+    $ yarn build
+
+.. _yarn: https://yarnpkg.com/lang/en/docs/install/
+
+- Start React UI::
+
+    $ yarn start
+
+This will automatically open a browser with your react app.
+Now you can open App.js and make changes and you should see it reload changes to the UI automatically!
