Hello. there were difficulties with the study of the software. There is a Russian version, major developers are ethnic Russian, but unfortunately no video lessons in Russian,although the transfer would not be difficult for developers. I just can not find it? or a pangolin in Russia is not in demand? Instruction in Russian is a good, but it is difficult to understand what to do, step by step, rather than in the video. Or at least a text version of the video lessons that we could look at and read.
