In this page: https://docs.opnsense.org/manual/reverse_proxy.html, the documentation references Haproxy How-Tos: https://docs.opnsense.org/manual/how-tos/haproxy.html
But those How-Tos no longer exist.
This is also true for the web interface of the haproxy plugin, it refers to the same non-existent howtos.
This basically means that at the moment there is no opnsense haproxy documentation at all
Seems like it was removed because it was outdated:
https://github.com/opnsense/docs/commit/62d8fc19157b48a001dbb720587ed81c93e4143c
HAProxy plugin went through 4 major iterations. I'm not sure which version the docs that a core dev wrote (not the maintainer) referred to, but as such the information given wasn't matching reality anymore. So it was removed again.

That's a pity.
Because I can of course read the original HAproxy documentation, but that documentation describes how to use HAproxy config files and does not explain where to look in the opnsense UI.
I would be more than willing to create a pull request for updated documentation but that means that first I need to understand it myself :-)
It might be good to ask the maintainer beforehand if he intends to change it again and/or if he could help with getting the docs ready. Without this component I fear it will be another wasted effort.

Plugin maintainer here. I don't plan another overhaul of the HAProxy plugin GUI. ;D So if anyone wants to start building a documentation, yes, please go ahead. Or if you think that some information could be added to one of the "introduction" pages, please submit your suggestion on GitHub (https://github.com/opnsense/plugins/issues/new/choose)...
I may review documentation (GitHub pull requests), but I can't put any effort into writing documentation in the foreseeable future. That being said, there's some good documentation out there... (https://www.google.de/search?q=opnsense+haproxy)
