 # SwiftHTTPStatusCodes
 Swift enum wrapper for easier handling of HTTP status codes.
+
+All the [RF2616](http://www.ietf.org/rfc/rfc2616.txt) standard status codes are supported with a few added ones from the [Wikipedia page](http://en.wikipedia.org/wiki/List_of_HTTP_status_codes).
+
+## Helper methods
+
+There are `Bool` properties on the enum for checking if a status code is of a certain category:
+```swift
+isInformational
+isSuccess
+isRedirection
+isClientError
+isServerError
+```
+
+There is also an extension on `NSHTTPURLResponse` to obtain a status code enum directly and to `init` with one:
+```swift
+var statusCodeValue: HTTPStatusCode?
+init?(URL url: NSURL, statusCode: HTTPStatusCode, HTTPVersion: String?, headerFields: [NSObject : AnyObject]?)
+```
