Hey :) YES, I have tons of experience with CPanel and Wordpress and would love to provide you with documentation about this! Can you share exactly where you want to add it? :)
Essentially, it depends on how your page was developed , so if you can show it to me, I can guide you further
Oh and yes, if you will have ANY QUESTIONS even after COMPLETION of project, I'll help you with that too!!
Awaiting your reply for further details
