It would be helpful to have a link to this documentation in the left pane of the official Qubes documentation. (Or is there already one - at least, I did not find it?)
Suggestion to replace this content with something like the following:
The official documentation of Qubes OS (or core documentation) is the main source of documentation about Qubes OS specific software. The Community guides category is part of the external documentation. It can document how to use a different kind of software in Qubes OS (i.e. a VPN), some personal preferences, non-standard setups, scripts and so on.
If your guide is about something that should be in the official documentation instead, consider editing the documentation instead of posting a community guide.
