Wikicr is a Wiki that is programmed in Crystal-lang, a compiled and efficient language. Unlike many
modern wiki website (dokuwiki, etc.) it is much more simple: It only requires to have some common libraries on the system, the crystal compiler, and git.
There is many features already developed, and lots to program in the future. I put that here, if you want to take a look at a demo I just installed on my server: wiki.nephos.xyz
