 Quick Start Guide
 =================
 
-This quick start is provided to guide users through the steps required to install the IBM High Performance Computing (HPC) software stack on a cluster managed by xCAT. (*NOTE:* DO NOT copy and paste the following commands, xCAT built XLC and XLF partial kits, but all other HPC kits are built by HPC team, xCAT will not have any knowledges for their requirements and how to use them)
