+Asynchronous HTTP Responses
+===========================
+
+New in GCDWebServer 3.0 is the ability to process HTTP requests aysnchronously i.e. add handlers to the server that generate their ```GCDWebServerResponse``` asynchronously. This is achieved by adding handlers that use a ```GCDWebServerAsyncProcessBlock``` instead of a ```GCDWebServerProcessBlock```. Here's an example:
+
+***Synchronous version***
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                         processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
+  
+  GCDWebServerDataResponse* response = [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
+  return response;
+  
+}];
+```
+
+***Asynchronous version***
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                    asyncProcessBlock:^(GCDWebServerRequest* request, GCDWebServerCompletionBlock completionBlock) {
+  
+  // Do some async operation like network access or file I/O (simulated here using dispatch_after())
+  dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(3 * NSEC_PER_SEC)), dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+    GCDWebServerDataResponse* response = [GCDWebServerDataResponse responseWithHTML:@"<html><body><p>Hello World</p></body></html>"];
+    completionBlock(response);
+  });
+
+}];

 Handlers require 2 GCD blocks:
 * The ```GCDWebServerMatchBlock``` is called on every handler added to the ```GCDWebServer``` instance whenever a web request has started (i.e. HTTP headers have been received). It is passed the basic info for the web request (HTTP method, URL, headers...) and must decide if it wants to handle it or not. If yes, it must return a new ```GCDWebServerRequest``` instance (see above) created with this info. Otherwise, it simply returns nil.
-* The ```GCDWebServerProcessBlock``` is called after the web request has been fully received and is passed the ```GCDWebServerRequest``` instance created at the previous step. It must return a ```GCDWebServerResponse``` instance (see above) or nil on error, which will result in a 500 HTTP status code returned to the client. It's however recommended to return an instance of [GCDWebServerErrorResponse](GCDWebServer/Responses/GCDWebServerErrorResponse.h) on error so more useful information can be returned to the client.

 Debug Builds & Custom Logging
 =============================
 
-When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To disable this behavior, make sure to define the preprocessor constant ```NDEBUG``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```NDEBUG``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Release configuration (this is done automatically for you if you use CocoaPods).
+When building GCDWebServer in "Debug" mode versus "Release" mode, GCDWebServer logs a lot more information and also performs a number of internal consistency checks. To enable this behavior, define the preprocessor constant ```DEBUG=1``` when compiling GCDWebServer. In Xcode target settings, this can be done by adding ```DEBUG=1``` to the build setting ```GCC_PREPROCESSOR_DEFINITIONS``` when building in Debug configuration.
 
 It's also possible to replace the logging system used by GCDWebServer by a custom one. Simply define the preprocessor constant ```__GCDWEBSERVER_LOGGING_HEADER__``` to the name of a header file (e.g. "MyLogging.h") that defines these macros:
 
 ```
