-Contents:
+App creation and auth
+---------------------
+
+Before you can use the mastodon API, you have to register your application (which gets you a client key and client secret) 
+and then log in (which gets you an access token). These functions allow you to do those things.
+For convenience, once you have a client id, secret and access token, you can simply pass them to the constructor of the class, too!
+
+Note that while it is perfectly reasonable to log back in whenever your app starts, registering a new application on every 
+startup is not, so don't do that - instead, register an application once, and then persist your client id and secret. Convenience
+methods for this are provided.
