I like to document my personal experience and researches with/about ApostropheCMS.
You can find the humble beginnings here: https://docs.crstn.io/apos/
The question: May I use the Apostrophe logo for that and future projects (created with Apostrophe or documented on GitBook) to promote ApostropheCMS? I placed it upfront as an example for you, but I can remove it if you want.
As you can see, the user sees at first glance that my documentation is unofficial and I link to the official documentation for Apostrophe – aside from the forum and Stack Overflow.
Hope you will like it.
