 ## Getting Started
 
-You can head to the very short [Getting Started](https://github.com/Longi94/JavaSteam/wiki/Getting-started) page or take a look at the [samples](https://github.com/Longi94/JavaSteam/tree/master/javasteam-samples/src/main/java/in/dragonbra/javasteamsamples) to get you started with using this library.
