How do make entire Angular ng-grid editable?

Using the code below, you can make a column editable.

How do you make the entire grid editable? The docs say look at wiki. Where is the wiki??

you can enable an excel-style mode by setting "enableCellEdit: true" and "enableCellSelection: true" in > v2.0.0

The wiki on GitHub is in the subnav in the tabs; look over next to "issues" etc.
