+## Complex return types
+In some cases you have some even more complex type that you want to get from the response.
+In these cases you create a TypeReference and pass that to the getForType method.
+Here is an example:
+
+```groovy
+import se.alipsa.simplerest.*;
+import com.fasterxml.jackson.core.type.TypeReference;
+import java.util.Map;
+import java.util.List;
+
+var restClient = new RestClient();
+Response response = restClient.get("https://localhost:8080/api/info");
+Map<String, List<String>> info = response.getForType(new TypeReference<>(){});
+```
+
 ## Using simple-rest for REST/XML
 The Rest service response is assumed to be JSON. If you need to use REST/XML you need to
 1. Add a dependency to com.fasterxml.jackson.dataformat:jackson-dataformat-xml
