Leaving history aside, yum is the easiest way to install, update, and remove software from your Linux systems. This quick tutorial guides you through the steps but it is not a substitute for man yum. This tutorial would give you general usage while man page give a comprehensive documentation of yum's functionality. An added benefit of yum is that it calculates a programs dependencies and then it downloads and installs them for you.
