Adding ExternalAccessory.framework

The documentation I'm reading says:

1. Find the Frameworks folder name in the Groups & File section of Xcode.
2. Select Add, Existing Frameworks by pressing the right button of the mouse.
3. Select ExternalAccessory.framework under Frameworks and click on the Add button.

In the Project Navigator, I have right-clicked the Frameworks folder, but I don't see a way of adding an existing framework.

In XCode 4 you can add frameworks by:

• Click on the top-level project entry in the project navigator. This should cause the project settings to be shown in the main editor
• Select the target that depends on the framework you want. This should show you the settings for the specific target
• Expand the section labeled "Link Binary with Libraries" to see the frameworks and libraries being linked in
• Press the "+" button to add a framework
