and then add that to the run and cli docs

 By default, all containers have networking enabled and they can make any
 outgoing connections. The operator can completely disable networking
-with `docker run -n` which disables all incoming and
+with `docker run --net none` which disables all incoming and
 outgoing networking. In cases like this, you would perform I/O through
 files or STDIN/STDOUT only.
