 ## Docker Install
 To run Railsgoat with Docker you must first have [Docker](https://docs.docker.com/engine/installation/) and [Docker Compose](https://docs.docker.com/compose/install/) installed. Once those dependencies are installed, cd into the Railsgoat directory where you've cloned the code and run. Rails requires Compose **1.6.0** or above and require a Docker Engine of version **1.10.0** or above.
 
+For Mac Apple Silicon (ARM64) you must also have Rosetta install
