 Spring MVC Cache Control is an extension to [Spring MVC][spring_mvc] that aims to simplify implementing HTTP/1.1 Cache-Control headers for annotated MVC controllers.
 
-## Checkout and Build from Source
+## Usage
+
+### Add Spring MVC Cache Control as a dependency to your project.
+
+#### Maven Projects
+
+``` 
+<dependency>
+    <groupId>net.rossillo.mvc.cache</groupId>
+    <artifactId>spring-mvc-cache-control</artifactId>
+    <version>1.1.0-RELEASE</version>
+    <scope>compile</scope>
+</dependency>
+```
+
+#### Gradle Projects
+
+```
+compile 'net.rossillo.mvc.cache:spring-mvc-cache-control:1.1.0-RELEASE'
+```
+
+### Configuration
+
+Simply include `net.rossillo.spring.web.mvc.CacheControlHandlerInterceptor` in your Spring MVC `-servlet.xml` file:
+
+```
+<mvc:interceptors>
+    <bean class="net.rossillo.spring.web.mvc.CacheControlHandlerInterceptor" />
+</mvc:interceptors>
+````
+
+### Annotate Your Controllers
+
+Use the `@CacheControl` annoation on either (or both) type level `@Controller`s or method level `@RequestMapping`s. The handler interceptor will read the annotations and generate HTTP/1.1 complaint cache-control headers. For example:
+
+```
+@Controller
+public final class DemoController {
+
+	/**
+	 * Public home page, cacheable for 5 minutes.
+	 */
+	@CacheControl(maxAge = 300)
+	@RequestMapping({"/", "/home.do"})
+	public String handleHomePageRequest(Model model) {
+		...
+	}
+}
+```
+
+See our [spring-mvc-cache-control-demo][demo] project for full details.
