 Building
 --------
-UnifiedNlp can be built using Gradle. Current builds are done using Gradle 2.2, but other versions might work as well.
+UnifiedNlp can be easily built using Gradle.
 
-To build with Gradle, first download git submodules:
+    git clone https://github.com/microg/UnifiedNlp
+    cd UnifiedNlp
+    ./gradlew build
 
-	git submodule update --init

-AOSP Build system integration
------------------------------
-UnifiedNlp can be build as part of Android when building an Android ROM from source.
-Add this repo to your (local) manifest.xml, as well as the UnifiedNlpApi and extend the `PRODUCT_PACKAGES` variable with `NetworkLocation` for KitKat and `LegacyNetworkLocation` for Jelly Bean.
-
-You can also directly invoke the compilation of UnifiedNlp by calling `make UnifiedNlp` or `make NetworkLocation` (respectively `make LegacyNetworkLocation`) from the build system root.
-Note that you need to add [UnifiedNlpApi](https://github.com/microg/android_external_UnifiedNlpApi) and [MicroGUiTools](https://github.com/microg/android_external_MicroGUiTools) to the build system for UnifiedNlp to compile:
