Modify category description text in admin

Hello all,

I’m hoping someone can help me apply a filter to the categories description text in the admin. It currently reads:

Categories, unlike tags, can have a hierarchy. You might have a Jazz category, and under that have children categories for Bebop and Big Band. Totally optional.

I am trying to edit this to say something much more generic, as I’m working on a project for a non-profit that is very professional in nature. I have searched for filters and have tried creating something of my own, but with no success.

The default code currently resides in wp-admin/edit-tags.php and wp-admin/edit-tag-form.php.

My apologies if this quite simple – I’m not great with PHP.

Thanks in advance.
