This module is great I want only just one additional feature

I'd like to add a "profile" module (I have to search for it) where registered users can add simple informations about them like name, contacts, a presentation and a photo

Then I'd like to add a link to the user name in the repository module (in every file uploaded by the user) that takes to this profile page

Is this possible? What steps are required to do this?

modify the template.html file for the template you are using.

It is highly recommended that you make a copy of the template you are using, rename the copy and then use/edit the copy so that your changes are not overwritten when new builds of the module come out.
