+## Build from source
+
+If you wish to build from source, clone the repo and run gradle's `android:assembleDebug` and `desktop:dist` tasks for building the Android and Desktop binaries respectively:
+
+    $ git clone https://github.com/Spikatrix/Zoned
+    $ cd Zoned
+    $ ./gradlew android:assembleDebug // Android
+    $ ./gradlew desktop:dist          // Desktop
+
+(Use `gradlew.bat` if you're on Windows)
+
+You can then find the generated binaries at
+ - Desktop: `Zoned/desktop/build/libs/*.jar`
+ - Android: `Zoned/android/build/outputs/apk/debug/*.apk`
+
