 # KituraContracts
@@ -26,9 +26,45 @@
 
 KituraContracts is a library containing type definitions shared by client (e.g. [KituraKit](https://ibm-swift.github.io/KituraKit/)) and server (e.g. [Kitura](https://ibm-swift.github.io/Kitura)) code. These shared type definitions include [Codable Closure Aliases](https://ibm-swift.github.io/KituraContracts/Typealiases.html), [RequestError](https://ibm-swift.github.io/KituraContracts/Structs/RequestError.html), [QueryEncoder](https://ibm-swift.github.io/KituraContracts/Classes/QueryEncoder.html), [QueryDecoder](https://ibm-swift.github.io/KituraContracts/Classes/QueryDecoder.html), [Coder](https://ibm-swift.github.io/KituraContracts/Classes/Coder.html), [Identifier Protocol](https://ibm-swift.github.io/KituraContracts/Protocols/Identifier.html#/s:15KituraContracts10IdentifierP5valueSSv) and [Extensions](https://ibm-swift.github.io/KituraContracts/Extensions.html#/s:SS) to String and Int, which add conformity to the Identifier protocol.
 
+## Getting Started
+
+To use KituraContracts, import the package:
+
+````swift
+import KituraContracts
+````
+
+KituraContracts represents the types and protocols that are common to both the [Kitura](https://github.com/IBM-Swift/Kitura) server and [KituraKit](https://github.com/IBM-Swift/KituraKit) client side library. If using Kitura or KituraKit, your project does not need to depend on KituraContracts explicitly.
+
+## Example
+
+This example, shows how to use a shared type definition for `RequestError` within a router POST method on `users`. If no errors occurred and you have a `User` you can respond with the user and pass nil as the `RequestError?` value. If there has been an error you can respond with an appropriate error and pass nil for the `User?`.
+
+````swift
+public struct User: Codable {
+    ...
+}
+
+router.post("/users") { (user: User, respondWith: (User?, RequestError?) -> Void) in
+
+    if databaseConnectionIsOk {
+        ...
+        respondWith(user, nil)
+    } else {
+        ...
+        respondWith(nil, .internalServerError)
+    }
+}
+````
