+===== Setup Features
+
+No matter which MockMvc builder you use all `MockMvcBuilder` implementations provide
+some common and very useful features. For example you can declare an `Accept` header
+for all requests and expect a status of 200 as well as a `Content-Type` header
+in all responses as follows:
+
+[source,java,indent=0]
+[subs="verbatim,quotes"]
+----
+// static import of MockMvcBuilders.standaloneSetup
+
+MockMVc mockMvc = standaloneSetup(new MusicController())
+		.defaultRequest(get("/").accept(MediaType.APPLICATION_JSON))
+		.alwaysExpect(status().isOk())
+		.alwaysExpect(content().contentType("application/json;charset=UTF-8"))
+		.build();
+----
+
+In addition 3rd party frameworks (and applications) may pre-package setup
+instructions like the ones through a `MockMvcConfigurer`. The Spring Framework
+has one such built-in implementation that helps to save and re-use the HTTP
+session across requests. It can be used as follows:
+
+[source,java,indent=0]
+[subs="verbatim,quotes"]
+----
+// static import of SharedHttpSessionConfigurer.sharedHttpSession
+
+MockMvc mockMvc = MockMvcBuilders.standaloneSetup(new TestController())
+        .apply(sharedHttpSession())
+        .build();

+// Use mockMvc to perform requests...
