Add Text on the plan subscription page

Hi! I need to create a div with some text (in different languages) below the title, on the plan subscription grid.
Which files do i need to change (html? php?)?
Do I have to create a variable on the languages file, so i can "dump" the translations?

Txs

Hi

It seems you are using plans list columns layout? If so, the file you have to modify would be components/com_osmembership/view/plan/tmpl/columns.php

And Yes, you will need to use language items (add these items into language file) so that you can translate it to all languages
