+# Natural Language Understanding
+
+## Installation
+
+##### Maven
+```xml
+<dependency>
+	<groupId>com.ibm.watson.developer_cloud</groupId>
+	<artifactId>natural-language-understanding</artifactId>
+	<version>3.7.1</version>
+</dependency>
+```
+
+##### Gradle
+```gradle
+'com.ibm.watson.developer_cloud:natural-language-understanding:3.7.1'
+```
+
+## Usage
+Use [Natural Language Understanding](http://www.ibm.com/watson/developercloud/doc/natural-language-understanding/index.html)
+to analyze various features of text content at scale. Provide text, raw HTML, or a public URL, and IBM Watson Natural
+Language Understanding will give you results for the features you request. The service cleans HTML content before
+analysis by default, so the results can ignore most advertisements and other unwanted content.
+
+```java
+NaturalLanguageUnderstanding service = new NaturalLanguageUnderstanding();
+service.setUsernameAndPassword("<username>", "<password>");
+
+EntitiesOptions entities = new EntitiesOptions.Builder().sentiment(true).limit(1).build();
+Features features = new Features.Builder().entities(entities).build();
+AnalyzeOptions parameters = new AnalyzeOptions.Builder().url("www.cnn.com").features(features).build();
+AnalysisResults results = service.analyze(parameters).execute();
+```
