  That's best, yes.

  Good to hear.

  The "man" pages are pretty minimal, because they're not meant to be huge.

https://www.freeradius.org/documentation/freeradius-server/3.2.8/

  And

https://www.freeradius.org/documentation/freeradius-server/3.2.8/unlang/xlat/index.html

  All of that documentation is included with the server source, under the doc/antora directory.  It should probably also be installed as a "freeradius-doc" package.

  The documentation for v4 is pretty exhaustive.  We're actively working on updates.
