 ## Opus-NT
 A windows homebrew kit and collection of mods. Can mod .WIM (this is where main-support is) and offline windows installations. Mods are written for 7 and up, but are likely to work with Vista and up. **Certain parts are still untested, so bear with me.**
 
-**DON'T RUN MULTIPLE INSTANCES OF THIS SCRIPT.**
