This ended up turning out excellent. I love the use of screenshots throughout your user documentation. Not only that but I like how you put pictures of what the buttons will look like because I know that is a main problem for users and following instructions. One key thing usability is keeping the interface consistent and I believe this software along with your instructions will keep the users on track. Your content is rich and thick and does a good job describing detail and important steps throughout the instructions. The only thing I beleive you are missing is some sort of conclusion. Whether it brings the instruction set to a close or it tells the user how the software can be used for more things and to read the actual manual or something like that. Other than that excellent work.
