 Simply run:
 
 ```
-docker run -d -p 80:80 -e TARGET_SERVER=<proxy location> mikesplain/nginx-proxy-pass
+docker run -d -p 80:80 -e HTTP_PROTOCOL=<protocol> -e TARGET_SERVER=<proxy location> mikesplain/nginx-proxy-pass

 For example, want to proxy everything to google? WHY NOT?!
 
 ```
-docker run -d -p 80:80 -e TARGET_SERVER=google.com mikesplain/nginx-proxy-pass
+docker run -d -p 80:80 -e HTTP_PROTOCOL=https -e TARGET_SERVER=google.com mikesplain/nginx-proxy-pass

 Or maybe another server on your network:
 
 ```
-docker run -d -p 80:80 -e TARGET_SERVER=192.168.8.15:8080 mikesplain/nginx-proxy-pass
