 #### Docker (Recommended)
 
 Docker is the recommended way to run a webserver that hosts Siren and can be

 `docker` is required to be installed with the service running.
 
-The docker image can be built and run via the Makefile by running:

 ```
-$ make docker

+The docker image can be built and run with the following commands:

-$ docker build -t siren .
