 ## En-ROADS Wrapper
 
-En-ROADS is a climate change simulator developed by [Climate Interactive](https://www.climateinteractive.org/). We have created a wrapper around the SDK to make it simple to use in a Python application which can be found in `enroadspy`. See `enroads_runner.py` for the main class that runs the SDK. The SDK is not included in this repository and access to it is very limited. If you would like to use this code, please contact Project Resilience at [daniel.young2@cognizant.com](mailto:daniel.young2@cognizant.com).
