Hello, my name is Federico, i'm interested as the title says, how programming trainers work?
which programming skills or other skill do i need? can someone help me to understand?
thanks
there is no single language to make trainers in.
You can try to use cosmos here and ask questions in that forum here to get started.
mostly this site is about selling trainers already made, not necessarily teaching how to do it.
however, there may be members here willing to help in the forum, especially the Cosmos forum.
best,
Cal
