+Producing your first bleep!
+---------------------------
+
+This sketch is the hello world of embedded interactive audio. Better known as bleep, it 
+produces a sine tone.
+
+The frequency of the sine tone is determined by a global variable, `gFrequency` 
+(line 12). The sine tone is produced by incrementing the phase of a sin function 
+on every audio frame.
+
+In render() you'll see a nested for loop structure. You'll see this in all Bela projects. 
+The first for loop cycles through 'audioFrames', the second through 'audioChannels' (in this case left 0 and right 1). 
+It is good to familiarise yourself with this structure as it's fundamental to producing sound with the system.
