 # devstack
 
 Get up and running quickly with edX services.
+
+## Getting Started
+
+All of the services can be run by following the steps below.
+
+1. Run the provision command, if you haven't already, to configure the various services with super-users (for
+   development without the auth service) and tenants (for multi-tenancy).
+
+   The username and password for the superusers are both "edx". You can access the services directly via Django admin
+   at the `/admin` path.
+
+    ```
+    $ make devstack.provision
+    ```
+
+2. Start the services.
+
+    ```
+    $ make devstack.start
+    ```
+
+After the services have started, if you need shell access to one of the services, run `make devstack.open.<service>`.
+
+```
+$ make devstack.open.discovery
+```

provision.sh

+#!/usr/bin/env bash
+
+# Ensure the containers are started
+docker-compose up -d
+
+# Create superusers that can access the services without the need for single sign-on
+# NOTE: If the users already exist, errors will be raised (in the Django shell), but execution of this provisioning
+# script will continue.
