This library is no longer maintained, as this implementation is generally frowned upon in the new Google Material design guidelines, excluding certain situations (like Google Keep type UI). See the new CardView APIs in the Support Library.

1. CardView (by Google): http://developer.android.com/training/material/lists-cards.html
2. Material design guidelines for the use of cards: http://www.google.com/design/spec/components/cards.html

To import the library into your project in Android Studio, add a new module to your main project and select "Import existing project".
