   For convenience, add PredictionIO's binary command path to your `PATH`, i.e.

  You can send these data to PredictionIO Event Server in real-time easily by
  making a HTTP request or through the `EventClient` of an SDK.
  
  To use the SDK, first install the SDK in the language of your choice - [Java](/sdk/java/), [PHP](/sdk/php), [Python](/sdk/python), or [Ruby](/sdk/ruby).
