For Windows Users

This a bit theoretical (untested, please correct me if I am wrong)

At a minimum you will need to java installed (preferably jdk1.7.0_45), you cannot rely on the version included with processing. You will also need a version of ruby installed, preferably jruby-1.7.9, which you can get here windows installer. You can get by with a regular ruby installation (at least version 1.9.3), but would need to use the --nojruby option on all sketches.

#Configuration# In addition to setting the processing root it may also be necessary to set the path to ruby-processing root RP5_HOME in the .rp5rc file. The post installer uses wget to download jruby-complete, however if you haven't got wget, you can manually download jruby-complete and put in the the vendors folder and re-run install_jruby_complete
