+* Add `'wagtail_airtable'` to your project's `INSTALLED_APPS`.
+    * To enable the snippet-specific import button on the Snippet list view, you'll want to make sure `wagtail_airtable` is above `wagtail.snippets` in your `INSTALLED_APPS`
 * In your settings you will need to map models to Airtable settings. Every model you want to map to an Airtable sheet will need:
     * An `AIRTABLE_BASE_KEY`. You can find the base key in your Airtable docs when you're signed in to Airtable.com
     * An `AIRTABLE_TABLE_NAME` to determine which table to connect to.
