This is the Pronunciation Guide, on the first tab is an explanation of the tone numbers and some sample sounds for each tone. I made this the first section, because Cantonese is crazy and tones are insane. :) That and I'm not used to tone numbers, I'm used to even more crazy silent H's and different accent marks.
And on the subsequent tabs is descriptions on how to pronounce the various letters that are used in jyutping, organized according to where they fall within the word (Start, Middle, and End).
