 -------------------------
 
 The library is pushed to Maven Central as a AAR, so you just need to add the following dependency to your `build.gradle`.
-
-    dependencies {
-        compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar:3.1.2'
-    }
+
+```groovy  
+dependencies {
+    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar:3.1.2'
+}
+```
 
 If your project doesn't use the stock action bar, but one of the compatibility implementations, you would use the following:
 
-    dependencies {
-        // Use the following if your project uses ActionBarCompat
-        compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abc:3.1.2'
-        // Or the following if your project uses ActionBarSherlock
-        compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abs:3.1.2'
-    }
+```groovy
+dependencies {
+    // Use the following if your project uses ActionBarCompat
+    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abc:3.1.2'
+    // Or the following if your project uses ActionBarSherlock
+    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abs:3.1.2'
