Can someone please explain to me how to apply the stuff from Github into Minecraft? Dumb question, I know, but my coding experiences go as far as importing images into an HTML document (and even that I sometimes can't get to work).
wrong place to seek the knowledge , here are some tips
how to set up Java SDK
how to compile minecraft mod
how to set up Git for windows
how to set up gradle
how to install and set up eclipse
Sounds complicated. Will it be backwards compatible though? Or will it work only on the most recent version?
Github is a source code repository , where people share and work on developing a software program . You will need to learn how to compile that code to make a usable mod . You can modify the code to use on any Minecraft version .
Use the compiled Jar mods that people have posted here and back a few pages . you will find version from 1.10.2 - 1.12.2
