Sandbox
-------------------------------------------------------------------------------
-To jump start development with an Apache Hadoop single node cluster, [DataTorrent Sandbox](https://www.datatorrent.com/download) powered by VirtualBox is available on Windows, Linux, or Mac platforms. The sandbox is configured by default to run with 6GB RAM; if your development machine has 16GB or more, you can increase the sandbox RAM to 8GB or more using the VirtualBox console. This will yield better performance and support larger applications. The advantage of developing in the sandbox is that most of the tools (e.g. _jdk_, _git_, _maven_), Hadoop YARN and HDFS, and a distribution of Apache Apex and DataTorrent RTS are pre-installed. The disadvantage is that the sandbox is a memory-limited environment, and requires settings changes and restarts to adjust memory available for development and testing.
+To jump-start development with Apex, please refer to the [Downloads](https://apex.apache.org/downloads.html) section of the Apache Apex website, which provides a list of 3rd party Apex binary packages and sandbox environments.
