I'm reading through the Force.com Canvas Developer's Guide and on page #17, I see the following instructions:
1. In Salesforce, from Setup, enter Apps in the Quick Find box, then select Apps.
2. In the Connected Apps related list, click New.

However, I don't see a "New" button in the Connected Apps list:
I have checked to ensure that I have "Customize Application" and "Modify All Data" permissions.
