A fork is just a program based on minetest. If the creator of the fork makes a build of the fork, installing is just like installing official minetest: just download, extract and run. With other forks you will have to compile it yourself. Instructions for compiling are in the readme.txt, which is shown towards the bottom of the github page for minetest and most forks. The patchset page has a list of code waiting to be considered, usually in the form of a fork.
