-== Name ==
-''Yum'' means ''Yellowdog updater, modified''. There used to be a ''yup'' tool, which stood for ''yellowdog updater''. Yum is a complete rewrite of yup.
-== Usage ==
-Like most package managers, yum is quite simple to use. It requires root privileges in order to install and remove packages.
-=== Installing packages ===
-To install a package, issue:
-<pre># yum install <package></pre>
-=== Uninstalling packages ===
-To remove a package from the system, issue:
-<pre># yum remove <package></pre>
-=== Updates ===
-Yum supports updating individual packages or the entire system at once.
-==== Full system update ====

-Sometimes, yum will fail to resolve dependencies for various reasons. You can use the <code>--skip-broken</code> option to skip packages whose dependencies could not be resolved:

-To update an individual package, simply pass its name as the argument:
