donho/npp-usermanual ? reverse-engineered prompt

Build me a clean documentation website for the Notepad++ user manual. It should be a simple, easy to browse site with sections for getting started, editing, searching, views, sessions, macros, plugins, preferences, themes, command line, and the other manual topics in the README.

I want it to feel like an official help site, with a clear sidebar or table of contents, readable article pages, and good navigation between sections. It should also be easy to run locally so I can preview changes in a browser while editing the content. If you need to look up current Hugo docs or best practices for the theme, go ahead and use the latest info online.

Please keep it organized so contributors can add or update documentation without breaking the layout, and make sure the site works well as a static documentation site.
