This collection of videos teaches you how to use [KeystoneJS](https://v5.keystonejs.com) to build a CRUD-ready GraphQL API, coming with an automatically generated Admin UI. 

Starting with a blank file, we will create an API by:
- defining "Lists" as content types
- adding fields (Select, Text, Checkbox, ...) to our lists
- customising access control to define what users can (and cannot!) do with our API.

In this lesson, we create a todo app via the Keystone 5 CLI, which gives us a GraphQL API with CRUD operation and  powerful filtering mechanisms, as well as a beautiful Admin UI.

In this lesson, we create a couple of KeystoneJS Lists. We will give the lists a name, which Keystone will use to automatically generate GraphQL queries and mutations. We will then query items and create new items from the GraphQL Playground.

Model your API data with Lists and Fields in KeystoneJS

In this lesson, we see how we can create initial data in our database. Our `keystone` instance has an async `onConnect` method that will run when a successful connection has been made to the database. We hook into that and create new items with `keystone.createItems()`.

In this lesson, we take a list of Dogs created in Keystone, and use the "Select" field type to add a "breed" field for each dog. We look at three different syntaxes to pass a list of options to the Select field, and how they affect the Admin UI.
