+### Usage
+
+See our [wiki](https://github.com/2dust/v2rayNG/wiki)
+
+### Development guide
+
+Android project under V2rayNG folder can be compiled directly in Android Studio, or using Gradle wrapper. But the v2ray core inside the aar is (probably) outdated.  
+The aar can be compiled from the Golang project under AndroidLibV2rayLite folder. For a quick start, read guide for [Go Mobile](https://github.com/golang/go/wiki/Mobile)
+and [Makefiles for Go Developers](https://tutorialedge.net/golang/makefiles-for-go-developers/)
+
+v2rayNG can run on Android Emulators, with minimum Android 5.0
