# Introduction
-This module will always require and load to the lastest compliance tester we have in the community modules.
-Currently this is [mod_compliance_2023].
+This meta-module will always `require` (and therefore auto-load) the lastest compliance tester we have in the community modules.
+Currently this is [mod_compliance_2023]. See the linked module for further details.
+
+If you do not use the *Prosody plugin installer* this module will likely have limited value to you.
+You can also just install the current compliance tester manually.
# Configuration
-Just load this module as any other module and it will automatically install [mod_compliance_2023] if you use the Prosody plugin installer.
-See the linked module for further details.
+Just load this module as any other module and it will automatically install and load [mod_compliance_2023] if you use the *Prosody plugin installer*.
