In part (1), last step: change make demo to “make demo-swarm”

In part (3), add a note saying that this works and tested only on Linux.

In part(4), remove the information about running contiv-ui. It’s already running by default. Feel free to add a line saying that all the policies and other objects can be created using the UI as well.
