rubyfu/RubyFu ? reverse-engineered prompt

Build me a polished book style website for a project called Rubyfu, with a strong dark and hacker inspired look, but still easy to read.

It should feel like an online handbook for Ruby security tricks, with a clear home page, a table of contents, and separate sections for basic Ruby, system tasks, network work, web topics, exploitation, forensics, and OSINT. I want the chapters to be easy to browse and read on desktop and mobile, with nice typography, a cover image, and simple navigation between sections.

Please include pages for contributors, FAQs, references, and required gems, and make the whole thing feel like a real publishable guide. Use the existing images and style assets where it makes sense, and keep the layout clean and consistent. If you need to look up current docs or best practices for the static site setup, feel free to do that.
