designing in toonboom

I am a character designer and am familiarizing myself for the first time with toon boom ( I am using a trial version of studio) I am basically just practicing sketching and cleaning up designs to get used to things but would like to understand when and how the mouth charts are created. I just feel this would help me greatly complete character as i do intend working in a studio enviroment and will need to know this. Any direction to tutorials etc would be appreciated alot.

In the F1 Help Guide of your Toon Boom Studio trial, you can find detailed information in Chapter 12 Sound and Lip-sync which includes how to map lip-sync drawings to a mouth chart on page 319.
