Welcome to Guitar Tricks..
If you follow fundamentals 1 & 2 in the core lessons you will find what you need. There is no difference between the theory on either type of guitar. What you learn on one can be applied to the other.
You didn't mention which instructor you are interested in learning from, but I would suggest Lisa McCormick. She does have tutorial on Strumming and Finger Style for accoustic guitar. Also so, Christopher Schiegel has a few easy Classical lessons the can be applied to acoustic guitar.
I hope this helps you out.
