 A simple, yet fast JSON library. Developed for the OpenKitten ecosystem, it is created to feel like it belongs to the ecosystem as well as the programming language.
 
+Cheetah's aim is to be a performant parser/serializer and to provide a good API.
+
+## Usage
+
+Import this dependency into your Package.swift 
+
+`.Package(url: "https://github.com/OpenKitten/Cheetah.git", majorVersion: 1)`
+
+Deserialize from UTF-8 bytes representing a JSON String:
+
+```swift
+let array = JSONArray(from: bytes)
+let object = JSONObject(from: bytes)
+```
+
+Deserialize from a Swift String JSON:
+```swift
+let array = JSONArray(from: bytes)
+let object = JSONObject(from: bytes)
+```
+
+Access values in an array like you would in Swift Arrays and values in an object like a Dictionary.
+
+```swift
+let favouriteNumber = favouriteNumbers[0]
+let usernameValue = userObject["username"]
+```
+
+Extract types with simplicity:
+
+```swift
+let username = String(userObject["username"]) // "Joannis"
+let isOnline = Bool(userObject["online"]) // true
+let age = Int(userObject["age"]) // 20
+let pi = Double(userObject["pi_constant"]) // 3.14
+```
+
+Chain subscripts easily to find results without a hassle as shown underneath:
+
+```json
+{
+  "users": [
+  	{
+  		"username": "Joannis",
+  		"profile": {
+  		  "firstName": "Joannis",
+  		  "lastName": "Orlandos"
+  		}
+  	},
+  	{
+  		"username": "Obbut",
+  		"profile": {
+  		  "firstName": "Robbert",
+  		  "lastName": "Brandsma"
+  		}
+  	}
+  ]
+}
+```
+
+```swift
+let obbutLastName = String(object["users"][1]["profile"]["lastName"]) // "Brandsma"
+```
