How do you change the settings for a mod in minecraft?

this is for manual installation, some mods come with installers

you could always just use an installer, MCPatcher works well

manual installation:

go to your .minecraft folder either by:

- go to Run and type %appdata% and press enter

- OR open Minecraft and before you log in click Options and click the hyperlink to Game location on disk

once in .minecraft open the bin folder and open minecraft.jar using an archive manager

open the mod file using an archive manager and drag all the files from the mod file to minecraft.jar

open Minecraft, if you get a black screen then either you haven't installed it correctly or if you have installed multiple mods, then they are incompatible with each other
