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).
