OK now that you have Arduino IDE set up, drivers installed if necessary and you've practiced uploading code, you can start installing all the Libraries we'll be using to program it.

A really excellent SD card library that gives a lot more capability than the default SD library
The Adafruit fork of the Audio library, install this with the Install ZIP Library... command
