-Getting Started
-***************
+Development
+-----------
 
-Prerequisites
-=============
+Start Devstack
+^^^^^^^^^^^^^^
 
-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.

-
-.. _relevant tutor-mfe documentation: https://github.com/overhangio/tutor-mfe#mfe-development

-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::
