+NSObject+NSCoding and Archiver
+------------------------------
+
+build by Kingiol
+
+[![Build Status](https://travis-ci.org/kingiol/NSObject-NSCoding.png?branch=master)](https://travis-ci.org/kingiol/NSObject-NSCoding)
+
+Mike Mayo
+Rackspace Mobile Apps

+twitter: @greenisus
+
+These are some simple classes to make object persistence with NSCoding easier.  This code was extracted from
+the Rackspace Cloud / OpenStack iOS app at http://launchpad.net/openstack-ios
+
+# Installation
+
+CocoaPods
+-
+
+NSObject-NSCoding is easiest to install using [CocoaPods](http://cocoapods.org).
+Simply add this line to your Podfile
+
+    pod 'NSObject-NSCoding'
+
+and run `pod install`
+
+Static
+-
+
+If you prefer not to use CocoaPods, simply drag `Archiver.h`, `Archiver.m`, `NSObject+NSCoding.h`, and `NSObject+NSCoding.m` into your project.
+
+Then, right click `Frameworks` in `Groups & Files` and choose `Add` -> `Existing Frameworks...` and choose `libobjc.A.dylib`.
+
+# Usage
+
+Archiver
+-
+
+This class will read and write objects that conform to the NSCoding protocol to disk.
+
+    SomeClass *myObject = [[[SomeClass alloc] init] autorelease];
+    myObject.someProperty = @"Hello world";
+
+    [Archiver persist:myObject key:@"myObject"];
+
+    // later on somewhere else...
+
+    SomeClass *myObject = [Archiver retrieve:@"myObject"];
+
+NSObject+NSCoding
+-
+
+This category simplifies implementing NSCoding by iterating over the properties of your
+class and encoding/decoding them for you.  It persists primitives (such as ints and floats)
+as well as any objects that conform to NSCoding.
+
+In your class header, conform to NSCoding:
+
+    @interface Model : NSObject <NSCoding>
+
+In your class implementation, call the automatic methods:
+
+    - (void)encodeWithCoder:(NSCoder *)coder {
+       [self autoEncodeWithCoder:coder];
+    }
+
+    - (id)initWithCoder:(NSCoder *)coder {
+        if (self = [super init]) {
+            [self autoDecode:coder];
+        }
+        return self;
+    }
