+This Jackson extension handles reading and writing of data encoded in [Smile](https://github.com/FasterXML/smile-format-specification)
+data format ("binary JSON").
 It extends standard Jackson streaming API (`JsonFactory`, `JsonParser`, `JsonGenerator`), and as such works seamlessly with all the higher level data abstractions (data binding, tree model, and pluggable extensions).

 ## Status
 
-Module has been mature since Jackson 1.6.
+Module has been mature since Jackson 1.6, and is used widely ([over 150 projects](http://mvnrepository.com/artifact/com.fasterxml.jackson.dataformat/jackson-dataformat-smile)), often as a dynamically configurable alternative to textual JSON.
+
+It also works very well for use cases like caching, especially when databinding is configured to
+[serialize POJOs as Arrays](https://medium.com/@cowtowncoder/serializing-java-pojo-as-json-array-with-jackson-2-more-compact-output-510a85c019d4) which can further reduce size of serialized objects.

 Basic usage is by using `SmileFactory` in places where you would usually use `JsonFactory`:
 
 ```java
-SmileFactory f = new SmileFactory();
-// can configure instance with 'SmileParser.Feature' and 'SmileGenerator.Feature'
-ObjectMapper mapper = new ObjectMapper(f);
-// and then read/write data as usual
+ObjectMapper mapper = new ObjectMapper(new SmileFactory());
