Here is a screencast on using Istanbul: http://glug-nith.org/~rishi/download/istanbul.ogg I have not added any audio to this, since I intend to get it translated into multiple languages. If you intend to lend your voice please let me know.

During the tutorial we created this video: http://glug-nith.org/~rishi/download/foo.ogg
