+********
+Purpose
+********
+
 This is the standard edX header for use in React applications. It has two exports:
 
 - **default**: The Header Component
 - **messages**: for i18n in the form of ``{ locale: { key: translatedString } }``
 
+Cloning and Startup
+===================
+
+.. code-block::
+
+
+  1. Clone your new repo:
+
+    ``git clone https://github.com/openedx/frontend-component-header-edx.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-component-header-edx && npm ci``
+
+  4. Start the dev server:
+
+    ``npm start``
+
