How do you add a watch module to an existing Android Studio project?

Issue

Google document "Creating and Running a Wearable App" (https://developer.android.com/training/wearables/apps/creating.html) only discussed how to create a project from scratch. Let's say if you already have an Android Studio project for phone/tablet (imported from Eclipse), how do you add a watch module for Android Wear?

Solution

Right click your project, open module settings, hit the + sign which will take you to a wizard in which you can add a wear module
