I hope you may know that DNF package manager is replaced the yum package manager in Fedora 22. Here are some examples on how to use DNF package manager.
It maintains CLI compatibility with yum, you would find no difference in using DNF.
You can still use YUM command, but all the commands will be redirected to respective DNF command. You will get similar output when you issue yum command.
Yum command has been deprecated, redirecting to '/usr/bin/dnf install httpd'
Packages can be installed using the following command.
# dnf install vsftpd
