What is the easiest way to add a new row to an ng-grid table using AngularJS?

I have an ng-grid table populated with data. I looked through the documentation and searched on Google, but I cannot find examples of how to add a new row to the grid.

Is there a special way that people use to add new data. I just hope to find some examples from which I can work. So far I have not found anything. I want the ng-grid site to have only one example. I am sure that I am not the only person who needs to add a row to the ng-grid.

thank
