Did you read own instructions?

I follow section "How to install/use" - added ref to Aero, added 'Page' DarkTheme.xaml, but project cannot compile, because inside it has "x:Class="REghZyFramework.Themes.DarkTheme" - what's that?? Theme - it's about styles, not about code. But if you add code, please describe where user can take it and where to put.
