 ## Running the UI Standalone
 
-After cloning the repository, run `make up-detached` in the `gradebook` directory - this will build and start the `gradebook` web application in a docker container.
+To install the project please refer to the [`edX Developer Stack`](https://github.com/edx/devstack) instructions.
 
-The web application runs on port **1991**, so when you go to `http://localhost:1991` you should see the UI.
+The web application runs on port **1994**, so when you go to `http://localhost:1994/course-v1:edX+DemoX+Demo_Course` you should see the UI (assuming you have such a Demo Course in your devstack).  Note that you always have to provide a course id to actually see a gradebook.
 
-If you don't, you can see the log messages for the docker container by executing `make logs` in the `gradebook` directory.
+If you don't, you can see the log messages for the docker container by executing `make gradebook-logs` in the `devstack` directory.
 
-Note that `make up-detached` executes the `npm run start` script which will hot-reload JavaScript and Sass files changes, so you should (:crossed_fingers:) not need to do anything (other than wait) when making changes.
+Note that starting the container executes the `npm run start` script which will hot-reload JavaScript and Sass files changes, so you should (:crossed_fingers:) not need to do anything (other than wait) when making changes.
+
+## Configuring for local use in edx-platform
+
+Assuming you've got the UI running at `http://localhost:1994`, you can configure the LMS in edx-platform
+to point to your local gradebook from the instructor dashboard by putting this settings in `lms/env/private.py`:
+```
+WRITABLE_GRADEBOOK_URL = 'http://localhost:1994'
+```
+
+There are also several edx-platform waffle and feature flags you'll have to enable from the Django admin:
+
+1. Grades > Persistent grades enabled flag.  Add this flag if it doesn't exist,
+check the ``enabled`` and ``enabled for all courses`` boxes.
+
+2. Waffle > Switches.  Add the ``grades.assume_zero_grade_if_absent`` switch and make it active.
+
+3. Waffle_utils > Waffle flag course overrides.  You want to activate this flag for any course
+in which you'd like to enable the gradebook.  Add a course override flag using a course id and the flag name
+``grades.writable_gradebook``.  Make sure to check the ``enabled`` box.  Alternatively, you could add this as a
+regular waffle flag to enable the gradebook for all courses.
+
+## Running tests
+
+1. Assuming that you're operating in the context of the edX devstack,
+run `gradebook-shell` from your devstack directory.  This will start a bash shell inside your
+running gradebook container.
+2. Run `make test` (which executes `npm run test`).  This will run all of the gradebook tests.

-### `.babelrc`
-
-We use [`Babel`](https://babeljs.io/) to transpile `ES2015+` JavaScript to `ES5` JavaScript. `ES5` JavaScript has [greater browser compatibility](http://kangax.github.io/compat-table/es5/) than [`ES2015+`](http://kangax.github.io/compat-table/es6/).
-
-The `.babelrc` file is used to specify a particular configuration - for example, we use the [`babel-preset-react`](https://babeljs.io/docs/plugins/preset-react/), which, among other things, allows `babel` to parse `JSX`.
-
-### `.dockerignore`
-
-The important thing to remember is to add the `node_modules` directory to `.dockerignore` - for more information [see the Docker documentation](https://docs.docker.com/engine/reference/builder/#dockerignore-file).
-
-### `.eslintignore`
-
-We use [`eslint`](https://eslint.org/) for our `JavaScript` linting needs. The `.eslintignore` file is used to [specify files or directories to, well, ignore](https://eslint.org/docs/user-guide/configuring#ignoring-files-and-directories).
-
-While `eslint` automatically ignores `node_modules`, we like to add it to the `.eslintignore` just for the added explicitness. In addition, you probably want to add the directory for your compiled files (in our case, `./dist`) and your coverage directory (in our case, `./coverage`).
-
-### `.eslintrc`
-
-This is where the actual `eslint` configuration is specified. All `edX` JavaScript projects should extend either the [`eslint-config-edx`](https://github.com/edx/eslint-config-edx/blob/master/packages/eslint-config-edx/README.md) or [`eslint-config-edx-es5`](https://github.com/edx/eslint-config-edx/blob/master/packages/eslint-config-edx-es5/README.md) configurations (for `ES2015+` and `ES5` JavaScript, respectively). Both configurations can be found in [the `eslint-config-edx` repository](https://github.com/edx/eslint-config-edx).
-
-### `.npmignore`
-
-We are not currently publishing this package to [`npm`](https://www.npmjs.com/). If we did, we would want to exclude certain files from getting uploaded to `npm` (like our coverage files, for example). For more information, see [the `npm` documentation](https://docs.npmjs.com/misc/developers#keeping-files-out-of-your-package).
-
-### `.travis.yml`
-
-We use [`Travis CI`](https://travis-ci.org/) to build (and deploy) our application. The `.travis.yml` file specifies the configuration for `Travis` builds. For more information, see [the `Travis` documentation](https://docs.travis-ci.com/user/customizing-the-build/).
-
-### `package.json`
-
-Arguably, one of the **most important files in an `npm`-based application**, the `package.json` file specifies everything from the `name` of the application, were it to be published to `npm`, to it's `dependencies`.
-
-For more information, see [the `npm` documentation](https://docs.npmjs.com/files/package.json).
-
-## Helpful Applications
-
-### [`Greenkeeper`](https://greenkeeper.io/)
-
-[`Greenkeeper`](https://greenkeeper.io/) is basically a `GitHub` application that handles `npm` dependencies. It will automatically open PRs with `package.json` updates when new versions of your `npm` dependencies get published. There are ways to also automatically keep the `package-lock.json` in-line, in the same PR, using [`greenkeeper-lockfile`].
-
-For more information, see [the `Greenkeeper` documentation](https://greenkeeper.io/docs.html#what-greenkeeper-does).

+Usage of the bulk-update API
+============================
+
+Context
+=======
+
+The LMS Grades API exposes a set of Gradebook-related endpoints:
+https://github.com/edx/edx-platform/blob/master/lms/djangoapps/grades/api/v1/gradebook_views.py
+The ``bulk-update`` endpoint defined therein allows for the creation/modification of subsection
+grades for multiple users and sections in a single request.  This allows clients of the API to limit
+the number of network requests made and to more easily manage client-side data.  Moreover,
+the course grade updates that occur during calls to this API are synchronous - the entire update operation
+is completed before a response is given to the client.
+
+For decisions made about the implementation of this API, see:
+https://github.com/edx/edx-platform/blob/master/lms/djangoapps/grades/docs/decisions/0001-gradebook-api.rst
+
+Decision
+========
+
+The Gradebook front-end will post data about a single subsection and user in a single request
+to the ``bulk-update`` API.  That is, we currently need only the "update" aspect of this
+endpoint, and not the "bulk" aspect, for satisfying the requirements of the current UX.
+
+Status
+======
+
+Accepted (circa December 2018)
+
+Consequences
+============
+
+This is a scenario in which the implementation of the API is coupled to the
+UX that depends on the API.  Because the course grade update is synchronous, it means
+the API response can contain the updated subsection and course grade data.  Because
+a response from the API contains this data, the UI can operate in a very familiar way:
+
+- A user clicks a button to submit a request with grade update data to the update endpoint.
+- On the server, the subsection and course grades are modified.
+- In the meantime, the client-side user looks at a spinner.
+- A response is returned with updated data and the spinner goes away.
+- Updated data is displayed to the user, along with a message indicative of the update.
+
+If the update becomes asynchronous, the user experience outlined above has to change.
+Because a single call to this endpoint updates grades data for only a single user,
+the endpoint does not necessarily have to utilize an asynchronous operation at this time.
