+ *  GCDWebServer provides its own built-in logging facility which is used by
+ *  default. It simply sends log messages to stderr assuming it is connected
+ *  to a terminal type device.
+ *
+ *  GCDWebServer is also compatible with a limited set of third-party logging
+ *  facilities. If one of them is available at compile time, GCDWebServer will
+ *  automatically use it in place of the built-in one.
+ *
+ *  Currently supported third-party logging facilities are:
+ *  - XLFacility (by the same author as GCDWebServer): https://github.com/swisspol/XLFacility
+ *  - CocoaLumberjack: https://github.com/CocoaLumberjack/CocoaLumberjack
+ *
+ *  For both the built-in logging facility and CocoaLumberjack, the default
+ *  logging level is INFO (or DEBUG if the preprocessor constant "DEBUG"
+ *  evaluates to non-zero at compile time).
+ *
+ *  It's possible to have GCDWebServer use a custom logging facility by defining
+ *  the "__GCDWEBSERVER_LOGGING_HEADER__" preprocessor constant in Xcode build
+ *  settings to the name of a custom header file (escaped like \"MyLogging.h\").
+ *  This header file must define the following set of macros:
+ *
+ *    GWS_LOG_DEBUG(...)
+ *    GWS_LOG_VERBOSE(...)
+ *    GWS_LOG_INFO(...)
+ *    GWS_LOG_WARNING(...)
+ *    GWS_LOG_ERROR(...)
+ *    GWS_LOG_EXCEPTION(__EXCEPTION__)
+ *
+ *  IMPORTANT: Except for GWS_LOG_EXCEPTION() which gets passed an NSException,
+ *  these macros must behave like NSLog(). Furthermore the GWS_LOG_DEBUG() macro
+ *  should not do anything unless the preprocessor constant "DEBUG" evaluates to
+ *  non-zero.
+ *
+ *  The logging methods below send log messages to the same logging facility
+ *  used by GCDWebServer. They can be used for consistency wherever you interact
+ *  with GCDWebServer in your code (e.g. in the implementation of handlers).

+Asynchronous HTTP Responses
+===========================
+
+New in GCDWebServer 3.0 is the ability to process HTTP requests aysnchronously i.e. add handlers to the server which generate their ```GCDWebServerResponse``` asynchronously. This is achieved by adding handlers that use a ```GCDWebServerAsyncProcessBlock``` instead of a ```GCDWebServerProcessBlock```. Here's an example:
+
+**(Synchronous version)** The handler blocks while generating the HTTP response:
+```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)** The handler returns immediately and calls back GCDWebServer later with the generated HTTP response:
+```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);
+  });
+
+}];
+```
+
+**(Advanced asynchronous version)** The handler returns immediately a streamed HTTP response which itself generates its contents asynchronously:
+```objectivec
+[webServer addDefaultHandlerForMethod:@"GET"
+                         requestClass:[GCDWebServerRequest class]
+                         processBlock:^GCDWebServerResponse *(GCDWebServerRequest* request) {
+  
+  NSMutableArray* contents = [NSMutableArray arrayWithObjects:@"<html><body><p>\n", @"Hello World!\n", @"</p></body></html>\n", nil];  // Fake data source we are reading from
+  GCDWebServerStreamedResponse* response = [GCDWebServerStreamedResponse responseWithContentType:@"text/html" asyncStreamBlock:^(GCDWebServerBodyReaderCompletionBlock completionBlock) {
+    
+    // Simulate a delay reading from the fake data source
+    dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(1 * NSEC_PER_SEC)), dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
+      NSString* string = contents.firstObject;
+      if (string) {
+        [contents removeObjectAtIndex:0];
+        completionBlock([string dataUsingEncoding:NSUTF8StringEncoding], nil);  // Generate the 2nd part of the stream data
+      } else {
+        completionBlock([NSData data], nil);  // Must pass an empty NSData to signal the end of the stream
+      }
+    });
+    
+  }];
+  return response;
+  
+}];
+```
+
+*Note that you can even combine both the asynchronous and advanced asynchronous versions to return asynchronously an asynchronous HTTP response!*
 
 GCDWebServer & Background Mode for iOS Apps
 ===========================================
@@ -267,24 +334,16 @@ Fortunately, GCDWebServer does all of this automatically for you:
 
 HTTP connections are often initiated in batches (or bursts), for instance when loading a web page with multiple resources. This makes it difficult to accurately detect when the *very last* HTTP connection has been closed: it's possible 2 consecutive HTTP connections part of the same batch would be separated by a small delay instead of overlapping. It would be bad for the client if GCDWebServer suspended itself right in between. The ```GCDWebServerOption_ConnectedStateCoalescingInterval``` option solves this problem elegantly by forcing GCDWebServer to wait some extra delay before performing any action after the last HTTP connection has been closed, just in case a new HTTP connection is initiated within this delay.
 
-Debug Builds & Custom Logging
-=============================
+Logging in GCDWebServer
+=======================
 
-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).
+Both for debugging and informational purpose, GCDWebServer logs messages extensively whenever something happens. Furthermore, when building GCDWebServer in "Debug" mode versus "Release" mode, it logs even more information but 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. Finally, you can also control the logging verbosity at run time by calling ```+[GCDWebServer setLogLevel:]```.
 
-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:
+By default, all messages logged by GCDWebServer are sent to its built-in logging facility, which simply outputs to ```stderr``` (assuming a terminal type device is connected). In order to better integrate with the rest of your app or because of the amount of information logged, you might want to use another logging facility.
 
-```
-#define LOG_DEBUG(...)  // Should not do anything if NDEBUG is defined
-#define LOG_VERBOSE(...)
-#define LOG_INFO(...)
-#define LOG_WARNING(...)
-#define LOG_ERROR(...)
-#define LOG_EXCEPTION(__EXCEPTION__)
+GCDWebServer has automatic support for [XLFacility](https://github.com/swisspol/XLFacility) (by the same author as GCDWebServer and also open-source) and [CocoaLumberjack](https://github.com/CocoaLumberjack/CocoaLumberjack). If either of them is in the same Xcode project, GCDWebServer should use it automatically instead of the built-in logging facility (see [GCDWebServerPrivate.h](GCDWebServer/Core/GCDWebServerPrivate.h) for the implementation details).
 
-#define DCHECK(__CONDITION__)  // Should not do anything if NDEBUG is defined or abort if __CONDITION__ is false
-#define DNOT_REACHED()  // Should not do anything if NDEBUG is defined
-```
+It's also possible to use a custom logging facility - see [GCDWebServer.h](GCDWebServer/Core/GCDWebServer.h) for more information.
