+Android WifiRttScan Sample
+===================================
+
+Sample demonstrates best practices for using WifiRTT APIs in Android. Also, this is a a useful
+application for testing Wifi-RTT enabled phones and access points and validating the estimated
+distance is close to the actual distance between them.
+
+Introduction
+------------
+
+Steps for trying out the sample:
+* Compile and install the mobile app onto your mobile device (for mobile scenario).
+
+This sample demonstrates best practices for using the WifiRtt APIs in Android. The main activity
+lists all access points that are WifiRtt enabled using the [WifiManager][1]. By clicking on one of
+the access points, another activity will launch and initiate [RangingRequest][2] via the
+[WifiRttManager][3]. The activity will display many of the details returned from the access point
+including the distance between the access point and the phone.
