-some high level information about OpenJ9 components together with the command-line options and environment variables that you can use to configure the VM when you start your application. We expect further content to be contributed over time. Because OpenJ9 was contributed to the Eclipse Foundation by IBM, this content contains some links to additional information that forms part of the [IBM&reg; SDK, Java&trade; Technology Edition product documentation](https://www.ibm.com/support/knowledgecenter/SSYKE2/welcome_javasdk_family.html) in IBM Knowledge Center. That content supplements the documentation here until a more complete set of user documentation is available.
