On the ORCiD@UI page of this guide, click on the green Create or Connect button in the upper left-hand corner

You will be asked to sign in with your Hawk ID and Password (not Healthcare ID), after which you will be presented with a screen that will say if you already have an ORCiD connected to the University, whether you have an ORCiD but still need to connect it to the university, or need to create and connect your ORCiD. 

Follow the instructions, and then click on the URL to your ORCiD account:

You will then be presented with a login screen. If you are fully connected to the university, you should be able to use the "Institutional Account" to login with your Hawk ID and password. This is a good test to make sure you are fully connected to the university.
