-Getting Started
-***************
+Development
+-----------

-Prerequisites
-=============
-
-The `devstack`_ is currently recommended as a development environment for your
-new MFE.  If you start it with ``make dev.up.lms`` that should give you
-everything you need as a companion to this frontend.
-
-Note that it is also possible to use `Tutor`_ to develop an MFE.  You can refer
-to the `relevant tutor-mfe documentation`_ to get started using it.

+Start Devstack
+^^^^^^^^^^^^^^

 To use this application, `devstack <https://github.com/openedx/devstack>`__ must be running and you must be logged into it.

+- Run ``make dev.up.lms``
 - Visit http://localhost:2000/course/course-v1:edX+DemoX+Demo_Course to view the demo course.  You can replace ``course-v1:edX+DemoX+Demo_Course`` with a different course key.

-Cloning and Startup
-===================
-
-.. code-block::
-
-  1. Clone your new repo:
-
-    ``git clone https://github.com/openedx/frontend-app-learning.git``
-
-  2. Use node v18.x.
-
-    The current version of the micro-frontend build scripts support node 18.
-    Using other major versions of node *may* work, but this is unsupported.  For
-    convenience, this repository includes an .nvmrc file to help in setting the
-    correct node version via `nvm <https://github.com/nvm-sh/nvm>`_.
-
-  3. Install npm dependencies:
-
-    ``cd frontend-app-learning && npm ci``
-
-  4. Start the dev server:
-
-    ``npm start``
-
 Local module development
-=========================
+^^^^^^^^^^^^^^^^^^^^^^^^

 To develop locally on modules that are installed into this app, you'll need to create a ``module.config.js``
 file (which is git-ignored) that defines where to find your local modules, for instance::

 edX Developer Guide's section on
 `MFE applications <https://edx.readthedocs.io/projects/edx-developer-docs/en/latest/developers_guide/micro_frontends_in_open_edx.html>`_.

 Environment Variables

 This MFE is configured via environment variables supplied at build time.
 All micro-frontends have a shared set of required environment variables,

+/**
+ * We discovered an error in Firefox where - upon iframe load - React would cease to call any
+ * useEffect hooks until the user interacts with the page again.  This is particularly confusing
+ * when navigating between sequences, as the UI partially updates leaving the user in a nebulous
+ * state.
+ *
+ * We were able to solve this error by using a layout effect to update some component state, which
+ * executes synchronously on render.  Somehow this forces React to continue it's lifecycle
+ * immediately, rather than waiting for user interaction.  This layout effect could be anywhere in
+ * the parent tree, as far as we can tell - we chose to add a conspicuously 'load bearing' (that's
+ * a joke) one here so it wouldn't be accidentally removed elsewhere.
+ *
+ * If we remove this hook when one of these happens:
+ * 1. React figures out that there's an issue here and fixes a bug.
+ * 2. We cease to use an iframe for unit rendering.
+ * 3. Firefox figures out that there's an issue in their iframe loading and fixes a bug.
+ * 4. We stop supporting Firefox.
+ * 5. An enterprising engineer decides to create a repo that reproduces the problem, submits it to
+ *    Firefox/React for review, and they kindly help us figure out what in the world is happening
+ *    so  we can fix it.
+ *
+ * This hook depends on the unit id just to make sure it re-evaluates whenever the ID changes.  If
+ * we change whether or not the Unit component is re-mounted when the unit ID changes, this may
+ * become important, as this hook will otherwise only evaluate the useLayoutEffect once.

-/**
- * We discovered an error in Firefox where - upon iframe load - React would cease to call any
- * useEffect hooks until the user interacts with the page again.  This is particularly confusing
- * when navigating between sequences, as the UI partially updates leaving the user in a nebulous
- * state.
- *
- * We were able to solve this error by using a layout effect to update some component state, which
- * executes synchronously on render.  Somehow this forces React to continue it's lifecycle
- * immediately, rather than waiting for user interaction.  This layout effect could be anywhere in
- * the parent tree, as far as we can tell - we chose to add a conspicuously 'load bearing' (that's
- * a joke) one here so it wouldn't be accidentally removed elsewhere.
- *
- * If we remove this hook when one of these happens:
- * 1. React figures out that there's an issue here and fixes a bug.
- * 2. We cease to use an iframe for unit rendering.
- * 3. Firefox figures out that there's an issue in their iframe loading and fixes a bug.
- * 4. We stop supporting Firefox.
- * 5. An enterprising engineer decides to create a repo that reproduces the problem, submits it to
- *    Firefox/React for review, and they kindly help us figure out what in the world is happening
- *    so  we can fix it.
- *
- * This hook depends on the unit id just to make sure it re-evaluates whenever the ID changes.  If
- * we change whether or not the Unit component is re-mounted when the unit ID changes, this may
- * become important, as this hook will otherwise only evaluate the useLayoutEffect once.
