 -----------------
 
-- First you must create a database.
-- Execute sql "Aauth.sql" file in your database
-- Don't forget to change database connection setups from application/config/database.php
+- First open your database (or create one if you have not already done so)
+- Execute sql "Aauth_v2.sql" file in your database
+- If you have not already, don't forget to change database connection settings in application/config/database.php
 
 That's All :)
