MkDocs

Simplicity and Ease of Use Straightforward Configuration: MkDocs has a simple and intuitive configuration file (usually mkdocs.yml). Compared to some document generation tools with complex features, beginners can quickly get started. They don't need to spend a lot of time learning complicated configuration syntax and numerous parameter options to easily set up a basic documentation site. For example, just by specifying the document directory structure, page titles, and other basic information, one can start writing content and generating a website, which is quite appealing to users who just want to focus on creating document content. Lightweight: It is a lightweight tool with a simple installation process. It doesn't rely on a large number of complex external libraries or running environments. Unlike some large documentation frameworks, it won't take up too much system resources and is relatively smooth and efficient during development and deployment. It's especially suitable for small projects or individuals who want to quickly organize knowledge documents and share them.

I use MkDocs with the Material theme for both work and personal projects. It's a great documentation tool: easy to get started, but has the potential to be very powerful if you need it to be. There's a good-sized community around it, including a lot of plugins.
