+# Reachability
+
+This is a drop-in replacement for Apples Reachability class. It is ARC compatible, uses the new GCD methods to notify of network interface changes.
+
+In addition to the standard NSNotification it supports the use of Blocks for when the network becomes reachable and unreachable.
+
+Finally you can specify wether or not a WWAN connection is considered "reachable".
+
+## A Simple example
+This sample uses Blocks to tell you when the interface state has changed. The blocks will be called on a BACKGROUND THREAD so you need to dispatch UI updates onto the main thread.
+
+	// allocate a reachability object
+	Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];
+
+	// set the blocks 
+	reach.reachableBlock = ^(Reachability*reach)
+	{
+		NSLog(@"REACHABLE!");
+	};
+
+	reach.unreachableBlock = ^(Reachability*reach)
+	{
+		NSLog(@"UNREACHABLE!");
+	};
+
+	// start the notifier which will cause the reachability object to retain itself!
+	[reach startNotifier];
+
+## Another simple example
+This sample will use NSNotifications to tell you when the interface has changed, they will be delivered on the MAIN THREAD so you *can* do UI updates from within the function.
+
+In addition it asks the Reachability object to consider the WWAN (3G/EDGE/CDMA) as a non-reachable connection (you might use this if you are writing a video streaming app, for example, to save the users data plan).
+
+	// allocate a reachability object
+	Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];
+
+	// tell the reachability that we DONT want to be reachable on 3G/EDGE/CDMA
+	reach.reachableOnWWAN = NO;
+	
+	// here we set up a NSNotification observer. The Reachability that caused the notification
+	// is passed in the object parameter
+	[[NSNotificationCenter defaultCenter] addObserver:self 
+											 selector:@selector(reachabilityChanged:) 
+												 name:kReachabilityChangedNotification 
+											   object:nil];
+											
+	[reach startNotifier]

+
+# ---------------------------------- #
+# CocoaPods Integration tests take 2 #
+# ---------------------------------- #
+
+#-----------------------------------------------------------------------------#
+
+# The following integrations tests are based on file comparison.
+#
+# 1.  For each test there is a folder with a `before` and `after` subfolders.
+# 2.  The contents of the before folder are copied to the `TMP_DIR` folder and
+#     then the given arguments are passed to the `POD_BINARY`.
+# 3.  After the pod command completes the execution the each file in the `after`
+#     subfolder is compared to be to the contents of the temporary directory.
+#     If the contents of the file do not match an error is registered. Xcode
+#     projects are compared in an UUID agnostic way.
+#
+# Notes:
+#
+# - The output of the pod command is saved in the `execution_output.txt` file
+#   which should be added to the Pods folders to test the CocoaPods UI.
+# - To create a new test, just create a before folder with the environment to
+#   test, copy it to the after folder and run the tested pod command inside.
+#   Then just add the tests below this files with the name of the folder and
+#   the arguments.
+#
+# Rationale:
+#
+# - Have a way to track precisely the evolution of the artifacts (and of the
+#   UI) produced by CocoaPods (git diff of the after folders).
+# - Allow uses to submit pull requests with the environment necessary to
+#   reproduce an issue.
+# - Have robust tests which don't depend on the programmatic interface of
+#   CocoaPods. These tests depend only the binary and its arguments an thus are
+#   suitable for testing CP regardless of the implementation (they could even
+#   work for an Objective-C one)
+
