+You'll need an integrated system and product for that system to be able to do much of anything. Once you've done initial setup, run these commands:
+
+* Create an integrated system: `./manage.py add_system <name> -d <description>`
+* Create a product: `./manage.py manage_product add -s <system name> --sku <an SKU> --name <name> --description <description> --price <price>`
+
+The `add_system` command will generate an API key for the system's use. You can add as many systems as you wish.
+
+> Alternatively, you can create these records through the Django Admin, but be advised that it won't create the API key for you. The management command uses a UUID for the key but any value will do, as long as it's unique.
+
+You can interact with the API directly through the Swagger interface: `<root url>/api/schema/swagger-ui/`
+
+The system also exposes a Redoc version of the API at `<root url>/api/schema/redoc/`

+Navigating to an API endpoint in the browser should also get you the normal DRF interface as well.
+
+> At this point we don't have API auth outside of Django sessions, so generated API keys don't do anything yet. There's no other frontend to this application at this point either.

 ### Running the app in a notebook
 
 This repo includes a config for running a [Jupyter notebook](https://jupyter.org/) in a Docker container. This enables you to do in a Jupyter notebook anything you might otherwise do in a Django shell. To get started:
