 # Macro Core
 
-Much quality. Many standards. The **Macro Core** library exists to save time and development effort! Herein ye shall find a veritable host of MIT-licenced, production quality SAS macros. These are a mix of tools, utilities, functions and code generators that are useful in the context of Application Development on the SAS platform (eg https://datacontroller.io). [Contributions](https://github.com/sasjs/core/blob/master/CONTRIBUTING.md) are welcomed.
