Your profile is a place to showcase your skills, projects, and achievements. You can add and edit your references from the References section in the resume generator. Other users can also add references to your profile, and so can you to theirs.
Visit their profile and click on the
Edit Reference button.
The button opens a popup like this:
submit to save your reference. You can always comeback and edit this. The owner can delete your reference if they so desire.
Just visit the References section in the resume generator and add a reference.
