[Plugin: Custom Contact Forms] Add headings and other html between inputs

I would like to be able to do this also.

I just want to add an intro below the h2 title header. Something like “Please fill out the form below … blah blah”

I don’t want to put the text in a form field; I just want to be able to add a paragraph. I see the many plugin files, but I have no idea which one to edit to add the text, or where to put the HTML. I looked through the previous posts and I can’t find where this has been addressed, although I see others would like to know as well.

Please advise. My client doesn’t understand why this can’t be done easily.
