This web app provides executable sample code for the core API methods provided by the CloudKit JS JavaScript library. 

Topics covered:

1. Authenticating users.

2. Retrieving users' discoverable information.

## Configuration

Before running the web app, modify the file *js/init.js*. Replace the container identifier with one that you own and insert an

API token generated through CloudKit Dashboard in the appropriate place. The web app assumes the existence of an **Items**

* location : Location

* asset : Asset

Create this record type through CloudKit Dashboard if it doesn't already exist.
