View source for Trouble setting up Admin password hash

Could someone help translate this documentation? I'm unsure what ~{{admin_recovery}} means as an end user. The docs don't really explain this at least not here. 

  1. to login define the ##recovery_password## in the **config/config.php** file first
    1. Call the ##""{{admin_recovery}}""## action as Admin and generate the password hash for your recovery_password
    1. Add the password hash: ##'recovery_password' => 'add hash here',##
  1. Don't forget to delete the _cache/config/**config.php** afterwards. (manually or via the ##admincache## action)
  1. Call yourwiki/admin.php
  1. Enter your recovery password
