Is there documentation for chown that is easier to understand?

Actually there is such documentation. Open a command line terminal - CtrlAltT and enter:

info chown

you will find this document uses less technical terms and phrasing, and explains the command in a more "conversational" manner. It is therefore easier to read and understand for beginner users.

After reading the info page I recommend familiarizing yourself with the man page for chown, because the man pages tend to be more succinct and complete.

I suggest installing tldr project:

$ tldr chown
# chown

Not supposed to post link only answers (for which I apologise) but I think this link might be what you are looking for as it explains things in simple detail with examples.
