+Quick Start Guide](https://spark.apache.org/docs/3.0.0/quick-start.html#self-contained-applications). 
 You'll learn what you need to set up your environment, how to write, package and execute a simple self-contained application.
 
 Prerequisites:
 - You need to have Java installed and have the JAVA_HOME environment variable pointing to the Java installation.
 - You need to have Apache Spark installed and have SPARK_HOME environment variable pointing to the Spark installation. 
-We recommend using Apache Spark 3.0.0-preview2 version. You can download it from the [Spark official website](https://spark.apache.org/downloads.html).
