+### Environment variables
+Use the following env variables to modify your stunnel configuration :
+
+- REDIS_PORT_6379_TCP_ADDR : hostname of Redis server endpoint
+- REDIS_PORT_6379_TCP_PORT : port of Redis server endpoint
+- REDIS_STUNNEL_CLIENT_MODE : [yes|no] client vs server mode
+
 ## Testing the Setup
 
 To test the `stunnel` setup, run the following NodeJS script. It should print out `[]` (an empty list) if it is a clean Redis server, but would otherwise print out all the keys on the server.
