Read tutorials, read AUMs, read the manual. Then start with something small, then bigger, and bigger, and bigger...

Okay, thank you. But I just have one last question:
since the AUMs and the Workshops are pretty recent, how did people learn without them? I still find it hard to believe that you can learn Lite-C (almost) in full just by reading a few Magazines and Workshops.

They are not recent. Before the AUMS conitec made workshops from the developers. I dont think anything from before the workshops exists to download as they are way out of date.

Oh, okay. Thank you very much for your help, everybody!
