Install instructions

Extract the ModTek\ directory inside the zip to BATTLETECH\Mods\ so you have various files under BATTLETECH\Mods\ModTek\.
Run the ModTekInjector.exe found now under BATTLETECH\Mods\ModTek\.
Run the game and verify that on the bottom left you see "W / MODTEK" next to the version number.
