+To use this library, you will need to run `composer install` from the root of the library, and then include the main library file, `wds-wp-rest-api-connect.php` and the composer autoloader, `vendor/autoload.php` from your plugin/theme.
 
 Once installed and activated, you'll need to create a '[Client Application](http://v2.wp-api.org/guide/authentication/#oauth-authentication)'.
 When you have the Client key and secret, you'll create a new `WDS_WP_REST_API\OAuth1\Connect` object by passing those credentials along with the REST API URL and the registered callback URL:
 ```php
+// Make sure you run `composer install`!
+require_once 'vendor/autoload.php';
+
+// include the library.
+require_once( 'wds-wp-rest-api-connect.php' );
+
 // Get the connect object
 $api_connect = new WDS_WP_REST_API\OAuth1\Connect();
