 2. Install

 3. Download and install [Maven](http://maven.apache.org/download.html). Also include the `bin`
 directory in Maven in `PATH`.

+5. Open a command shell (`cmd`) in the Spark directory and build Spark with [Maven](http://spark.apache.org/docs/latest/building-spark.html#building-with-buildmvn) and include the `-Psparkr` profile to build the R package. For example to use the default Hadoop versions you can run
+
+    ```bash
+    mvn.cmd -DskipTests -Psparkr package
+    ```
+
+    `.\build\mvn` is a shell script so `mvn.cmd` should be used directly on Windows.
