Add text/image on logon page

Dear Support, I have Xibo 3.2.1 for Docker.
I have followed this guide Themes | Xibo Digital Signage to modify the logo/text format etc. Is there a way to add add some text/image/links (tutorials) on Xibo login page? I would like to add it under the last line which shows version, source, about.

Any help would be much appreciated, thank you.
