 # Android GUI for [WireGuard](https://www.wireguard.com/)
 
-### [Test this app on the Play Store](https://play.google.com/apps/testing/com.wireguard.android).
+**[Download from the Play Store](https://play.google.com/store/apps/details?id=com.wireguard.android)**
 
 This is an Android GUI for [WireGuard](https://www.wireguard.com/). It [opportunistically uses the kernel implementation](https://git.zx2c4.com/android_kernel_wireguard/about/), and falls back to using the non-root [userspace implementation](https://git.zx2c4.com/wireguard-go/about/).
 
+## Building
+
+```
+$ git clone https://git.zx2c4.com/wireguard-android
+$ cd wireguard-android
+$ git submodule init
+$ git submodule update
+$ ./gradlew assembleRelease
+```
