LazHelp is a simple hypertext help system for Lazarus that only relies on LCL and can be used to embed simple help sites in Lazarus applications.
I wrote this some time ago and while i do add some features and fix bugs now and then, it is not a high priority project of mine as not many of my other projects use it.
You can download the latest version from here: lazhelp20200513125407.zip (208KB). It contains the LazHelp components, a LazHelp editor/previewer, an example application, a VIM highlighting script (i wrote that years ago, i do not know if it still works), API documentation, etc.
