The video was helpful. You should include more of these as part of your documentation. Honestly your documentation is not very helpful at all.
I have seen where to modify the code. It appears the theme doe not include a login or account register page, and these now need to be created, correct?
FYI I purchased your them because it was promoted to be easy to use for any skill level. This is not true. I have tried to do simple things like modifying the demo content, and find this is quite difficult to do without knowing the inner workings of WordPress themes and php. This is not easy for all skill levels.
