+
+Prerequisites
+============
+
+* Spark v2.0 or later
+* Java 7 or later
+* hivemall-spark-xxx-with-dependencies.jar
+*
[define-all.spark](https://github.com/apache/incubator-hivemall/blob/master/resources/ddl/define-all.spark)
+*
[import-packages.spark](https://github.com/apache/incubator-hivemall/blob/master/resources/ddl/import-packages.spark)
+
+Installation
+============
+
+First, you download a compiled Spark package from [the Spark official web
page](http://spark.apache.org/downloads.html) and
+invoke spark-shell with a compiled Hivemall binary.
+
+```
+$ ./bin/spark-shell --jars hivemall-spark-xxx-with-dependencies.jar
+```
+
+> #### Notice
+> If you would like to try Hivemall functions on the latest release of
Spark, you just say `bin/spark-shell` in a Hivemall package.
+> This command automatically downloads the latest Spark version, compiles
Hivemall for the version, and invokes spark-shell with the compiled Hivemall
binary.
+
+Then, you load scripts for Hivemall functions.
+
+```
+scala> :load define-all.spark
