-# Build
+## Code Contributions
+
+I am happy about any pull requests and appreciate your effort to help us developing OpenPGP Keychain :)
+Fork OpenPGP Keychain and do a merge request. I will help with occuring problems and merge your changes back into the main project.
 
 ## Build with Gradle
 
 1. Have Android SDK "tools", "platform-tools", and "build-tools" directories in your PATH (http://developer.android.com/sdk/index.html)
 2. Export ANDROID_HOME pointing to your Android SDK
-3. Install gradle
-4. Execute ``gradle wrapper`` (http://www.gradle.org/docs/current/userguide/gradle_wrapper.html)
-5. Execute ``./gradlew build``
-
-## Build with Ant
-
-1. Have Android SDK "tools" directory in your PATH (http://developer.android.com/sdk/index.html)
-2. Execute ``android update project -p OpenPGP-Keychain``
-3. Execute ``android update project -p libraries/ActionBarSherlock``
-3. Execute ``android update project -p libraries/HtmlTextView``
-3. Execute ``cd OpenPGP-Kechain``, ``ant debug``
-
-# Contribute

-Fork OpenPGP Keychain and do a merge request. I will merge your changes back into the main project.
+3. Download Android Support Repository, and Google Repository using Android SDK Manager
+4. Execute ``./gradlew build``
 
 ## Development with Eclipse
 
 Android Studio is currently not supported or recommended!
