How do I install minecraft Forge?
I figured it out after asking.
I started out by going to: https://files.minecraftforge.net/
then I downloaded it to the desktop (I used 1.10 version, but that doesn't really matter)
then i used then commands in this order
$ cd Desktop
$ java -jar jarfilename.jar
And now it's modded. .;,;. (I used the command to launch the jar file due to me not being able to do so any other way on my computer).
