How to Install

Upgrade an Existing Community

If you haven't already, create a constants.php file and add the following line:

<?php
define( 'USE_DEVELOPMENT_BUILDS', TRUE );

Then go to AdminCP → System → Applications and click Check for Updates, and the beta will become available for you to upgrade in the normal way. Your community will show you all future betas while that line is in the constants.php file.
