 Nearby Connections is a high level protocol on top of Bluetooth/WiFi that acts
 as a medium-agnostic socket. Devices are able to advertise, scan, and connect

+# Building Nearby, Unit Testing and Sample Apps
+We support multiple platforms including Linux, iOS & Windows. The ultimate goal is to build from source. The offical build system we support is [bazel] (https://bazel.build). Before that is accomplished, we provide precompiled libraries as stop-gap solutions. See the following pages for platform specific instructions.

+# Building Nearby on IOS
+
+We do not yet support build from source. Instead a prebuilt library is provided. See [this link](https://github.com/google/nearby/tree/master/cpp/platform/impl/ios/Example/NearbyConnectionsExample/README.md) for a sample app using the prebuilt library.
