I am new here; I am a teacher and I came across this forum in search of help in starting how to use the scheduling program. Thank you
Hello and welcome!
There is this (a bit old) manual by Volker: https://www.timetabling.de/manual/FET-manual.en.html
You need to add subjects, teachers, students (add a year and divide it by categories, or add to it groups and subgroups directly), activities, rooms, buildings, time constraints, and space constraints. Generate.
