Could there be an article to read related to getting started with My Talk?

For example, I am a daughter of a man who suffered from a stroke many years ago who has not had an alternative form of communication for years.  Since finding My Talk I have been excited to try this program with him.  I was looking for an article on your site that might give me some tips on not just how to use My Talk, but perhaps a step by step guide with suggestions on the size and type of board that is best suited for beginners to help us get started.  How many cells are reccomended for new users?  Any other tips or strategies to encourage new users to "buy-in" to using it (especially in this case as he has been reluctant with other forms of alternative communication).  Just a thought.
