[NTG-context] SciTE Setup in Windows and .rb scripts

Hi I am new to ConTeXt. Once I saw the showcase, I thought that this is even much better than LaTeX which I have been using for 3 years. I have MikTeX installed on my WinXP machine and according to the advice tried to setup SciTE to write some practice documents. Still I have problems. I have done everything in SCiTE in ConTeXt manual, but I can't still compile my files. I have to go to command line and do it manually. Should I install Ruby on my machine? What is Ruby for anyway? Where should I get those .rb scripts and where should I put them? Keep up the good work, Cheers, Hooman
