ArrowChat

Upgradeing to ArrowChat v3.0.2

The last instruction says to rename the file /arrowchat/includes/integration.php.

Does it mean I need to override the current code in /arrowchat/includes/integration.php ? with the code in this file /arrowchat/includes/functions/integrations/functions_smf_v2.php ?

SMF Integration:
Take the /arrowchat/includes/functions/integrations/functions_smf_v2.php file and rename it to /arrowchat/includes/integration.php

Yes, but only if you are using SMF (Simple machines forum)
