Log in to your account and tap or click "My Documents" in the sidebar on the right. Click the three dots under the resume you want to duplicate, and click "Duplicate". This will create a copy of your resume.
Tip:
We recommend that you always have a generic version of your resume and then create multiple copies which you can edit and tailor to specific job descriptions. In this way, even if you delete one copy by mistake, you won't loose all your data.
