+#### I need VNC to a Remote Host (Secure)
+
+Now you can direct connect VNC to any image!
+
+Add the following line:
+
+`-e EXTRA="-display none -vnc 0.0.0.0:99,password"`
+
+In the Docker terminal, press `enter` until you see `(qemu)`.
+
+Type `change vnc password`
+
+`ip n` will usually show the container IP first.
+
+Port is `5999`.
+
+Now VNC connect using the Docker container IP, for example `172.17.0.2:5999`
+
+You can also find the container IP: `docker inspect <containerid> | jq -r '.[0].NetworkSettings.IPAddress'`
+
+Remote VNC over SSH: `ssh -N root@1.1.1.1 -L  5999:172.17.0.2:5999`, where `1.1.1.1` is your remote server IP and `172.17.0.2` is your LAN container IP.
+
+#### I need VNC on localhost (Local use only!)
+
+##### VNC Insecure
+
+**NOT TLS/HTTPS Encrypted at all!**
+```
+-p 5999:5999
+-e EXTRA="-display none -vnc 0.0.0.0:99,password"
+```
+VNC Connect to `localhost:5999`.
+
+Or `ssh -N root@1.1.1.1 -L  5999:127.0.0.1:5999`, where `1.1.1.1` is your remote server IP.
+
+(Note: if you close port 5999 and use the SSH tunnel, this becomes secure.)

 #### I have used Docker-OSX before and wish to extract my Mac OS X image.
 
 Use `docker commit`, copy the ID, and then run `docker start -ai <Replace this with your ID>`.
