 ## Install and Run PredictionIO
-First you need to [install PredictionIO 0.9.1](http://docs.prediction.io/install/) (if you haven't done it).
+First you need to [install PredictionIO 0.12.1](https://predictionio.apache.org/install/) (if you haven't done it).
 Let's say you have installed PredictionIO at /home/yourname/PredictionIO/. For convenience, add PredictionIO's binary command path to your PATH, i.e. /home/yourname/PredictionIO/bin
 ```
 $ PATH=$PATH:/home/yourname/PredictionIO/bin; export PATH
