To access the ResourceFirst Administration Center, simply click the wrench icon on the far right of the main icon tray (highlighted in blue below). If you don't see the icon, it means you're not authorized as an administrator.
Once you click the icon, you'll see the Administration menu bar, as illustrated below.
The Administration menu includes a variety of features for configuring your ResourceFirst system. See the other articles in this section to walk through them one by one.
