     ### IDE Setup (Optional)
     You can get your preferred IDE ready for Gearpump by following [this guide](dev-ide-setup.html).
     
    -### Define Processor(Task) class and Partitioner class
    +### Decide which language and API to use for writing 
    +Gearpump supports two level APIs:
     
    -An application is a Directed Acyclic Graph (DAG) of processors. In the wordcount example,
We will firstly define two processors `Split` and `Sum`, and then weave them together.
    +1. Low level API, which is more similar to Akka programming, operating on each event.
The API document can be found at [Low Level API Doc](http://www.gearpump.io/releases/latest/api/scala/index.html#io.gearpump.streaming.package).
    +
    +2. High level API (aka DSL), which is operating on streaming instead of individual event.
The API document can be found at [DSL API Doc](http://www.gearpump.io/releases/latest/api/scala/index.html#io.gearpump.streaming.dsl.package).
    +
    +And both APIs have their Java version and Scala version.
    +
    +So, before you writing our first Gearpump application, you need to decide which API to
use and which language to use.

have both Scala version and Java version.
