      3. Add your site at https://account.mybrickfield.ie/mysites
      4. Open https://MOODLE/admin/tool/brickfield/registration.php and fill API key and secret from the setup above

      Test:

      1. Put attached bulkadd.php in admin/tool/brickfield directory
      2. Run the script several times (5 should be more than enough)
      3. Run 

        php admin/cli/scheduled_task.php --execute='\tool_brickfield\task\update_summarydata'

Ensure that task runs successfully

      In the event of extremely large numbers of content areas present on a site or with low memory limits on PHP, this can result in long processing times or fatal errors during the 'update_summarydata' task. This is a performance issue.
