This is a system that I develop and maintain for years and use it on various multiyear projects that usually have 300+ pages of documentation of various types - functional specification, infrastructure, user manuals etc. The system bundles up many different tools and frameworks you may need in doing such task and which would take a lot of time to setup correctly. You could add it to your CI/CD pipeline for continuous documentation delivery to various environments and end user groups while still allowing them to download entire thing for offline use.
