Make sure to first have SuperBLT, and BeardLib installed. Click the links in the dependency list.

Optional video tutorial for installing SuperBLT, BeardLib, and mod_overrides mods: https://youtu.be/rin_sjSJIkg

1. After downloading the mod, use a program such as 7zip or WinRAR to extract the main folder of the mod.
2. Drop that folder into the mods folder which is supposed to be in the game's installation folder (don't know where that is? click here)

Drag into your mod_overrides folder. mod_overrides should be found in the assets folder. If not, create the folder yourself, and then drag the mod there.

Here is a video you can watch if you are lost. It helped me!
