When I want to say that I have added some kind of detail, reference or whatever piece of information about my profile, work experience, etc. to my resumé, and it is just a sheet-long document, I should say "on my resumé".
But, what if there are several sheets. I think I should say "in the resumé"
I am not sure.
In any case, might I use the first formula for the two possibilities?
You add things to your resume.
You list things on or in your resume.
You talk about things on or in your resume.
