 ## 1.1 Configure your server
 
 We recommend you to start with a fresh installation of OS (either RHEL or Ubuntu). You have to install realtime kernel on your operating system. Based on your operating system you can search how to install realtime kernel. Once the realtime kernel is installed then you have to change the boot arguments. You can use `tuned` command for this or you can do it manually via re-building the grub.
