PlantUML
PlantUML for GitHub is a browser extension that turns text descriptions of diagrams into pictures directly on GitHub pages, so people can see the drawing instead of the code. It is aimed mainly at software developers and technical writers who put diagrams in their projects.
How hard it is to start using it. Easy: install it like a normal app, or use it in your browser. Advanced: you run it on your own server, use the command line, or it is a tool for developers.
