The Fedora Project is in constant need for administrators with better skills. In a yet-to-be-named initiative, the Fedora Project wishes to help as many contributors as possible improve their basic system administration skills. This study guide is to help those pursuing additional goals, including higher-pay, certifications and more.

The study guide is intended to be printed by those who wish to study common tasks performed by many system administrators. This study guide is based upon the Red Hat Certified System Administrator Exam Objectives. Other useful study components will be added here. Community contributions are always welcome.
