I guess its up to me. That was one of the /very/ first things I did with the new roboRIO even before tank drive (being a 2nd year First'er and a 1 year VEX'er). After finding the javadocs it was very easy. I found the java docs

here. I have yet to find any kind of built in acceleromoter in the new roboRIO but MESSAGE ME IF YOU FIND ONE!!! Oh and you probably want smartdashboard stuff too!! I forgot!! The stuff hasn't changed since last year in regards to the smartdashboard but the new javadocs are
here the rest you might want to find in screensteps from the 2014 cRIO.
