+##Basic, block based, text transitions
 
 NRTextTransitions is a category in UIView that makes easier handling animated text transitions for UILabel, UITextView and UITextField. As the standard +[UIView animateWithDuration:animations:] is not able to animate non-animatable properties, and text, font and textColor properties of UILabel, UITextView and UITextField, are non-animatable, you need to use CATransition to do so with animation.
 
 NRTextTransitions uses a similar API to the standard UIView class methods, encapsulating the changes passed in the `animations` parameter block. In order to apply the transitions to the objects mentioned in this block, you **MUST** create an array, add the objects to this array, and pass it in the 'textObjects' parameter.
 
-#Example
+##Example
+
+```
+	exampleLabel.text = @"I'm the old text!";
+    exampleLabel.backgroundColor = [UIColor whiteColor];
+    
+    [UIView animateTextTransitionForObjects:@[exampleLabel] withDuration:0.75 delay:0 animations:^{
+	    	exampleLabel.text = @"And I'm animated!";
+    } completion:^{    	
+	    	exampleLabel.backgroundColor = [UIColor colorWithWhite:0.8 alpha:0.5];
+    }];
+```
+
