Good going there, looks nice. I like the addition of pictures; I can make the missing one for you when I have time. I still have a few remarks:
- It's not clear what the user should download.
- Extending point 1: dlls-externals-mandatory-pack.rar is not obvious either (not directly related of course)
- Nothing about the special language (processes, frames).
- Maybe link to beginner's tutorial
- "Although officially it is only supported on Windows and Linux" -> I didn't know this
- Picture should be explained a bit, maybe a caption like "here we see blabla".
