I fully agree with Ralph.
However, I still think that what we are missing are examples for users that are maybe less interested in writing their own code but want to try out and hopefully then use what is provided.
Also, it is important for people who set up and manage the systems and infrastructure to understand the configuration options, how e.g., the channel search works, etc.
PVXS documentation is good, but it is not easy for a new user to get started and figure out what is currently there, what pieces of documentation to read, or if there is something in
the first place.
The CA manual could use (read: severely needs, IMO) an update as well, but as of now there is very little if anything to help a new, or even experienced EPICS user to get started using
PVA.
Which I find is a great pity; a lot of nice things can be done by using the group PVs with QSRV and JSON configuration.

Is there a PVAccess reference manual (a la CA)? I have been trying to use the protocol specification page in github, but it would be great if there was something covering PVAccess
from a higher level perspective.
I would recommend PVXS [1] as client (and server) library. The older implementations that are currently shipped as part of Base will be phased out.
PVXS has pretty decent documentation. [2]
