You don't need to learn xml, just read the docs included with LS, and you should do fine, joeblade.com has an "uber-tutorial" that will take you from start to finish and it's a great jumping off point for newbs (believe me). one thing i've noticed is that the docs are a little incorrect or outdated, so simply connect to irc.freenet.net #litestep on IRC, and someone should be able to answer your questions, but just try it out before you ask.
