 ## Overview
 
-To use the API, you need to create an instance of the `Otf` class, providing your email address and password. This will authenticate you with the API and allow you to make requests. When the `Otf` object is created it automatically grabs your member details and home studio, to simplify the process of making requests.

+You can either pass an `OtfUser` object to the `OtfClass` or you can pass nothing and allow it to prompt you for your username and password.
 
-See the [examples](./examples) for more information on how to use the API.
+You can also export environment variables `OTF_EMAIL` and `OTF_PASSWORD` to get these from the environment.
