+`NSURLConnectionVCR` provides an easy way to record and re-play `NSURLConnection` requests/responses.
+By removing the dependency on external web servers, your tests will run fast and deterministic.
+Don't worry, no need to change your existing `NSURLConnection`-based code.
+`NSURLConnectionVCR` hooks into `NSURLConnection` by 'swizzling' implementations at run-time.
+This project is inspired on [Myron Marston's VCR for Ruby on Rails] [1].
+Getting Started
+First, start the VCR and give it a storage path:
+	[NSURLConnectionVCR startVCRWithPath:@"fixtures/vcr_cassettes" error:nil];
+Then perform a request using `NSURLConnection`:
+	NSURL* url = [NSURL URLWithString:@""];
+	NSURLRequest* request = [NSURLRequest requestWithURL:url];
+    NSHTTPURLResponse* response = nil;
+    NSData* data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:nil];
+The first time this code is run, it will run the request and store the response in a file at the specified path.
+Run it again, and VCR will 'play back' the recorded response from disk, without making a call to the web server.
+Optionally, stop the VCR once you're done:
+	[NSURLConnection stopVCRWithError:nil];
+Adding NSURLConnectionVCR to your project
+* Mac OS X 10.7 SDK or later
+* iOS 5.0 SDK or later
+* ARC (Automatic Reference Counting)
+Just add `NSURLConnectionVCR.m` and `NSURLConnectionVCR.h` to your project.
+There are no external dependencies, except of course Foundation.framework and the Objective C runtime.
+Quicklook plug-in
+`NSURLConnectionVCR` creates one file per unique request and stores it at the specified path.
+The provided Quicklook plug-in makes basic inspection of these cache files convenient.
+A cache file is basically an archive containing the `NSURLResponse` and `NSData` that were returned when the request was done.
+The name of the cache file is the MD5 digest of the original `NSURLRequest`.
+The Quicklook preview displays the response data and puts the original URL and HTTP status code as title of the preview window.
