+## Installation
+
+`cpsms` is available [from PyPI](https://pypi.python.org/pypi/cpsms). Easiest
+way to install is: `pip install cpsms`.
+
+
+## Requirements
+
 You need to have a (paid) account at CPSMS to be able to use their gateway.
 They sell a fair, no-nonsense product which I'd recommend if you want to be
 able to send SMS from your code (primarily to Danish phones).
 
-HOW TO USE
-See a couple of example use cases in example.py that should have come
-along with this file. Apart from what is shown in examples.py, this also
-supports status callback URLs, delayed sending and flash messages.
 
-FURTHER INFO
-For more info on parameters, take a look at the API documentation found at:
-<https://www.cpsms.dk/login/index.php?page=dokumentation>.

 I believe the gateway software running at the CPSMS server is some sort of
 standard product. This may be able to talk to other remote SMS gateways as
