-Steps to run this sample in go/compose-samples-howto
\ No newline at end of file
+# Crane sample
+
+[Crane](https://material.io/design/material-studies/crane.html) is a travel app part of the Material
+Studies built with [Jetpack Compose](https://developer.android.com/jetpack/compose).
+The goal of the sample is to showcase Material components, draggable UI elements, Android Views
+inside Compose, and UI state handling.
+
+## Screenshots
+
+<img src="screenshots/crane.gif"/>
+
+## Features
+
+This sample contains 4 screens:
+- __Landing__ [screen][landing] that fades out after 2 seconds then slides the main content in from
+the bottom of the screen.
+- __Home__ [screen][home] where you can explore flights, hotels, and restaurants specifying
+the number of people.
+ - Clicking on the number of people refreshes the destinations.
+ - The [backdrop](https://material.io/components/backdrop) is draggable and can pin to the top of
+ the screen, just under the search criteria, and to the bottom. Implemented [here][backdrop].
+ - Destination's images are retrieved using the [coil-accompanist][coil-accompanist] library.
+- __Calendar__ [screen][calendar]. Tapping on __Select Dates__ takes you to a calendar built
+completely from scratch. It makes a heavy usage of Compose's state APIs.
+- Destination's __Details__ [screen][details]. When tapping on a destination, a new screen
+implemented using a different Activity will be displayed. In there, you can see the a `MapView`
+embedded in Compose and Compose buttons updating the Android View. Notice how you can also
+interact with the `MapView` seamlessly.
+
+## Google Maps SDK
+
+To get the MapView working, you need to get an API key as
+the [documentation says](https://developers.google.com/maps/documentation/android-sdk/get-api-key),
+and include it in the `local.properties` file as follows:
+
+```
+google.maps.key={insert_your_api_key_here}
+```
+
+## Data
+
+The data is hardcoded in the _CraneData_ [file][data] and exposed to the UI using the
+[MainViewModel][mainViewModel]. Image resources are retrieved from
+[Unsplash](https://unsplash.com/).
