 Disable assignment of IPv6 gateway IP.
 
+## Container creation options
+
+To use these options add `--network name=network_name,driver-opt=option=value,driver-opt=option=value`
+to the `docker run` invocation:
+
+```bash
+docker run -i -t --rm --network name=test,ip=192.168.1.1,driver-opt=gw4=192.168.0.1,driver-opt=gw6=fe80:: alpine
+```
+
+Available options:
+
+`gw4=IP`
+
+`gw6=IP`
+
+Forces assignment of a specified gateway (if one is not provided by the IPAM)
+when creating the interface. Useful for [pyipam](https://github.com/jacekkow/docker-plugin-pyipam)
+with "ptp=1,nogw=1" options.
+
+Using these would add routes:
+```
+default via IP dev eth0
+IP dev eth0 scope link
+```
+
