Gitlab pages administration documentation is confusing

The documentation at https://docs.gitlab.com/ee/pages/administration.html#nginx-configuration can be hard to follow. Most section cover two possible installation methods, one for source and one for omnibus making the page very busy. Additionally the NGINX caveats section only covers source installation.

It mentions “source” and “omnibus” caveats … but isn’t very clear if it includes ALL of the steps.

Would be a lot more helpful to have separate pages for source installs vs. omnibus
