+```java
+// Issues a GET to Google
+Response httpResponse = new Request("http://example.com")
+        .getResource();
+
+String responseBody = httpResponse.getBody();
+
+// 
+Response httpResponse = new Request("http://example.com")
+        .addHeader("x-my-header", "foobar")
+        .addQueryParameter("foo", "bar")
+        .getResource();
+
+String responseBody = httpResponse.getBody();
+
+// Posts a simple JSON object to the server
+Response httpResponse = new Request("http://example.com")
+        .addHeader("x-my-header", "foobar")
+        .addQueryParameter("foo", "bar")
