 This plugin for the Bukkit Minecraft Server API ([Homepage](http://bukkit.org) | [Github](https://github.com/Bukkit/Bukkit )) offers the possibility to access some playerstats via xml files. The provided data is basically generated by [Stats](https://github.com/nidefawl/Stats).
 
 ## Install
 
-To install the plugin, simply place the compiled **XmlStats.jar** in your servers plugin directory and execute the /reload-command on your server. The plugin will create it's config file in the /plugins/XmlStats directory. To enable the webserver of the plugin you have to edit the config.yml, set the following value and reload the server again:
-  
-    options.webserver-enabled: true

 ## Usage
 
 ### Game side
 
-At this time of the development you are only able to reload the plugin without reloading the whole server:

 For a list of all known players on your server:
 
-    http://server:port/users.xml

 For the added up stats of all known players:

+Or to fetch the stats of a list of users:
+

+You can combine these parameters, so you can receive the sum of some users and specific stats:
+

 To get data provided by the iConomy plugin:
     
-    http://server:port/money.xml
+    http://server:port/user_balances.xml?user=*
+    http://server:port/user_balances.xml?sum=*
