 ## Installation

-* Test if everything works by opening the website %YOUR_HOST%/PAFLib/test/index.php
+
+Add the following lines to your composer file:
+
+```json
+{
+  "repositories": [
+    {
+      "type": "vcs",
+      "url": "https://github.com/Simonsator/PartyAndFriends-PHP-Lib"

 ## Where to start
-If you don't know how to use this library have a look at the ["test/index.php"](https://github.com/Simonsator/PartyAndFriends-PHP-Lib/blob/master/PAFLib/test/index.php) and ["test/playerdatashow.php"](https://github.com/Simonsator/PartyAndFriends-PHP-Lib/blob/master/PAFLib/test/playerdatashow.php)
+
+A demo project can be found [here](https://github.com/Simonsator/PartyAndFriends-PHP-Lib-Demo). To get started, you
+should call the constructor of the class `Simonsator\PartyAndFriends\PAFPlayerManager`. You need to provide the table
+prefix used by Party And Friends and a PDO object with an active connection to the MySQL database which is used by Party
+And Friends. Using the methods of the `PAFPlayerManager` you can `PAFPlayer` objects, with which you can access data of
+players.
