  Everyone started somewhere.

  The server comes with a large amount of documentation.  Every configuration file contains extensive comments which describe what it does, and how it works.

  There's also a lot of documentation online:  https://www-fr.freeradius.org/documentation/freeradius-server/3.2.8/

  That site is built from the FreeRADIUS source.  It includes documentation on how FreeRADIUS works, RADIUS / AAA concepts, tutorials on how to configure the server, and many more.

$ ls raddb/mods-enabled

  And then read the files.  There is extensive documentation.

  You don't.  You read raddb/sites-available/default, and edit it for your needs.  Again, it contains extensive documentation.

  For basic introduction, see https://www-fr.freeradius.org/documentation/freeradius-server/3.2.8/concepts/session/processing.html

  Most beginning questions are answered in the documentation.  If you have specific questions that aren't addressed there, then ask a question here.  But basic questions about modules / operation are all documented.  It's best to spend some time reading that.  We're not going to "cut and paste" documentation from the web site onto the mailing list.  That isn't helpful.
