 The SocketLabs Email Delivery Ruby library allows you to easily send email messages via the [SocketLabs Injection API](https://www.socketlabs.com/docs/inject/).  The library makes it easy to build and send any type of message supported by the API, from a simple message to a single recipient all the way to a complex bulk message sent to a group of recipients with unique merge data per recipient.

 # Getting Started
 ## Obtaining your API Key and SocketLabs ServerId number
-In order to get started, you'll need to enable the Injection API feature in the [SocketLabs Control Panel](https://cp.socketlabs.com). 
-Once logged in, navigate to your SocketLabs server's dashboard (if you only have one server on your account you'll be taken here immediately after logging in). 
-Make note of your 4 or 5 digit ServerId number, as you'll need this along with 
-your API key in order to use the Injection API.
