wood r4 or ysmenu? What should I use and how?

Well maybe this is a very noob question, but since it's this old and I don't really see what to use with my flashcard i'll just ask.
I have a r4imax (from r4imax.com) and the more I search about what to use the less I get.
I suppose I have to use ysmenu, but then again, which version and where could I download it and what to do with it? I suppouse it's just copy files, but in other sites I've seen that in some r4 you need an installer or something...
Thanks in advance...
