-#### Environment Variables
+#### Environment variables
 
 Environment variables are available, as detailed below, to allow the operator to configure a container on run. Environment variable values cannot be changed after running the container; it's a one-shot type setting. If you need to change a value you have to terminate, (i.e stop and remove), and replace the running container.
