Noir is a framework for Stormworks: Build and Rescue designed to (metaphorically!) hold your hand in some areas with addon development, while also giving you a neat way of organizing your addon.
Noir contains built-in libraries that provide helpful functions to use throughout your code. They can be found in Noir.Libraries.
Noir also contains built-in services which can be found in Noir.Services or fetched directly via Noir.Services:GetService(name).
Finally, examples can be found in the examples directory.
Documentation can be found here.
For learning how to install and use Noir in your addon, please check out the documentation.
