+### Installation
+
+`composer require hazzard/cookie`
+
+### Usage
+
+```
+use Hazzard\Cookie\Cookie;
+
+// Set a cookie for 60 minutes.
+Cookie::set('name', 'value', 60);
+
+// Set a cookie "forever".
+Cookie::forever('name', 'value');
+
+// Retrieve a cookie.
+$value = Cookie::get('name');
+
+// Forget a cookie.
+Cookie::forget('name');
+```
+
+
+##### Default path and domain
+
+```
+Cookie::setDefaultPathAndDomain('/path/to', 'domain.com');
+```
+
+
+##### Encrypted cookies
+
+First `composer require hazzard/encryption`, then:
+
+```
+use Hazzard\Cookie\Cookie;
+use Hazzard\Encryption\Encrypter;
+
+$encrypter = new Encrypter('a random 32 character string', 'AES-256-CBC');
+
+Cookie::setEncrypter($encrypter);
+```
+
+You can use any other encrypter as long as it has the `encrypt` and `decrypt` methods.
