+
+Purpose
+*******
+
+The ORA Staff Grading App is a micro-frontend (MFE) staff grading experience
+for Open Response Assessments (ORAs). This experience was designed to
+streamline the grading process and enable richer previews of submission content
+and, eventually, replace on-platform grading workflows for ORA.
+
+When enabled, ORAs with a staff grading step will link to this new MFE when
+clicking "Grade Available Responses" from the ORA or link in the instructor
+dashboard.
+
+The ORA Staff Grader depends on the `lms/djangoapps/ora_staff_grader
+<https://github.com/openedx/edx-platform/tree/master/lms/djangoapps/ora_staff_grader>`_
+app in ``edx-platform``.
+
+Getting Started
+***************
+
+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
+
+Plugins
+=======
+This MFE can be customized using `Frontend Plugin Framework <https://github.com/openedx/frontend-plugin-framework>`_.
+
+The parts of this MFE that can be customized in that manner are documented `here </src/plugin-slots>`_.
+
+Developing
+==========
+
+Cloning and Startup
+--------------
+
+First, clone the repo, install code prerequisites, and start the app.
+
+.. code-block::
+
+
+  1. Clone your new repo:
+
+  ``git clone git@github.com:openedx/frontend-app-ora-grading.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-ora-grading && npm install``
+
+  4. Update the application port to use for local development:
+
+    Default port is 1993. If this does not work for you, update the line
+    `PORT=1993` to your port in all .env.* files
+
+  5. Start the dev server:
+
+    ``npm start``
+
+The app will, by default, run on `http://localhost:1993` unless otherwise
+specified in ``.env.development:PORT`` and ``.env.development:BASE_URL``.
+
+Next, enable the ORA Grading micro-frontend in `edx-platform`
+
+#. Add the path to the ORA Grading app in `edx-platform`:
+
+   #. Go to your environment settings (e.g. `edx-platform/lms/envs/private.py`)
+
+   #. Add the environment variable, ``ORA_GRADING_MICROFRONTEND_URL`` pointing
+      to the ORA Grading app location (e.g. ``http://localhost:1993``).
+
+#. Start / restart the ``edx-platform`` ``lms``.
+
+#. Enable the ORA Grading feature in Django Admin.
+
+   #. Go to Django Admin (`{lms-root}/admin`)
+
+   #. Navigate to ``django-waffle`` > ``Flags`` and click ``add/enable a new
+      flag``.
+
+   #. Add a new flag called ``openresponseassessment.enhanced_staff_grader``
+      and enable it.
+
+From there, visit an Open Response Assessment with a Staff Graded Step and
+click the "View and grade responses" button to begin grading in the ORA Staff
+Grader experience.
+
+
+Making Changes
+--------------
+
+Get / install the latest code:
+
+.. code-block::
+
+  # Grab the latest code
+  git checkout master
+  git pull
+
+  # Install/update the dev requirements
+  npm install
+
+
+Before committing:
+
+.. code-block::
+
+  # Make a new branch for your changes
+  git checkout -b <your_github_username>/<short_description>
+
+  # Using your favorite editor, edit the code to make your change.
+
+  # Run your new tests
+  npm test
+
+  # Commit all your changes
+  git commit ...
+  git push
+
+  # Open a PR and ask for review.
+
+Deploying

 What `make validate-no-uncommitted-package-lock-changes` does is `git diff`s for any `package-lock.json` file changes in your project.
 
 This is important because `npm` uses the pinned dependencies in your `package-lock.json` file to build the `node_modules` directory. However, the dependencies defined within the `package.json` file can be modified manually, for example, to become misaligned with the dependencies defined within the `package-lock.json`. So when `npm install` executes, the `package-lock.json` file will be updated to mirror the modified `package.json` changes.
