*DNF* is a software package manager that installs, updates, and removes
link:package[packages] on RPM-based Linux distributions. It
automatically computes dependencies and determines the actions required
to install packages. DNF also makes it easier to maintain groups of
machines, eliminating the need to manually update each one using rpm.
Introduced in Fedora 18, it has been the default package manager since
Fedora 22.

DNF or Dandified yum is the next generation version of yum. It roughly
maintains CLI compatibility with yum and defines a strict API for
extensions and plugins. Plugins can modify or extend features of DNF or
provide additional CLI commands on top of those mentioned below. If you
know the name of such a command (including commands mentioned bellow),
you may find/install the package which provides it using the appropriate
virtual provide in the form of dnf-command() where is the name of the
command; e.g. dnf-command(repoquery) for a repoquery command (the same
applies to specifying dependencies of packages that require a particular
command).
