 # Swikly PHP SDK
 
+Swikly provides a new and easy way to request the equivalent to a down payment or security deposit (we call that "a swik") but with no funds being transferred.
+
+When you request a swik, you're effectively asking your customer to provide a credit card hold, specifying an amount and a period during which the deposit will be held.
+
+This allows you to secure your bookings or request a down payment or security deposit remotely, simply, and with complete confidence. Swikly also provides a payment option which is cheaper than most of its competitors.
+
 You can sign up to get a [Swikly](https://www.swikly.com) account [here](https://www.swikly.com/user_signup_self.php).
