WordPress theme and plugin to create user guide

I wish to create an interactive user guide using WordPress with images, videos etc. I have tried to read about it online and found a plugin called Documentor

However, I was wondering if there was a complete theme that I could use. I wish to make it interactive, intuitive and visually appealing.

It would be great if anyone could suggest a theme/plugin that would help me get there
