+### Lite API
+
+The library gives the possibility to use the [Lite API](https://ipinfo.io/developers/lite-api) too, authentication with your token is still required.
+
+The returned details are slightly different from the Core API.
+
+To use the Lite API you must use the `IPinfoLiteSpring`, it works in the same way as the `IPinfoSpring` class.
+
+```java
+    IPinfoLiteSpring ipinfoSpring = new IPinfoLiteSpring.Builder()
+        // Set the IPinfo instance. By default we provide one, however you're
+        // allowed to change this here. Also provide your IPinfo Access Token here.
+        .setIPinfo(new IPinfoLite.Builder().setToken("IPINFO ACCESS TOKEN").build())
+        // Set the InterceptorStrategy. By default we use
+        // BotInterceptorStrategy.
+        .interceptorStrategy(new BotInterceptorStrategy())
+        // Set the IPStrategy. By default we use SimpleIPStrategy.
+        .ipStrategy(new SimpleIPStrategy())
+        // Set the AttributeStrategy. By default we use SessionAttributeStrategy.
+        .attributeStrategy(new SessionAttributeStrategy())
+        // Finally build it.
+        .build();

 ### Other Libraries
 
 There are [official IPinfo client libraries](https://ipinfo.io/developers/libraries) available for many languages including PHP, Python, Go, Java, Ruby, and many popular frameworks such as Django, Rails, and Laravel. There are also many third-party libraries and integrations available for our API.
