So i'm a homebrew n00b. I've never used a homebrew app before. So my question, what do I need to do to make it work on my R4? I would want to use DSO. Do I need to install some type of firmware or software before using it? What is this Moonshell thing. Yes, yes, I know i'm a damn n00b when it comes to this. Please don't verbally abuse me too much lol.
