refactor: Update README.rst

Part of https://github.com/openedx/axim-engineering/issues/23

This updates the `@edx/brand` alias to point to the `brand-openedx` package at
the `openedx` scope. This does not impact imports because this package is used
via an alias.

+***************
+Getting Started
+***************
 
-Start Devstack
-^^^^^^^^^^^^^^
+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.
+
+.. _Devstack: https://github.com/openedx/devstack
+
+.. _Tutor: https://github.com/overhangio/tutor
+
+.. _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
