+Start working on your Flink Scala program in a few simple steps.
+
+## Startup Flink interactive Scala shell
+
+Flink has an integrated interactive scala shell.
+It can be used in a local setup as well as in a cluster setup.
+
+To use it in a local setup just execute:
+
+__Sample Input__:
+~~~bash
+flink/bin/start-scala-shell.sh
+~~~
+
+And it will initialize a local JobManager by itself.
+
+To use it in a cluster setup you can supply the host and port of the
JobManager with:
+
+__Sample Input__:
+~~~bash
+flink/bin/start-scala-shell.sh -host "<hostname>" -port <portnumber>
+~~~
+
+
+## Usage
+
+The shell will prebind the ExecutionEnvironment as "env", so far only
batch mode is supported.
+
+The following example will execute the wordcount program in the scala
shell:
+
+~~~scala
+Flink-Shell> val text = env.fromElements("To be, or not to be,--that is
the question:--","Whether 'tis nobler in the mind to suffer", "The slings and
arrows of outrageous fortune","Or to take arms against a sea of troubles,")
+Flink-Shell> val counts = text.flatMap { _.toLowerCase.split("\\W+") }.map
{ (_, 1) }.groupBy(0).sum(1)
+Flink-Shell> counts.print()
+~~~
+
+
+The print() command will automatically send the specified tasks to the
JobManager for execution and will show the result of the computation in the
terminal.
+
+It is possbile to write results to a file, like in the standard Scala api.
However, in this case you need to call, to run your program:
+
+~~~scala
+Flink-Shell> env.execute("MyProgram")
+~~~
+
+The Flink Shell comes with command history and autocompletion.

The file is using `Scala` in upper and lowercase variants. I would make
them all uppercase.
