Oh yes, you read correctly. Yum is out of business and has been replaced by dnf
with the release of Fedora 22. The commands and functionality remain (almost) the same. So just type dnf wherever you typed yum before.
dnf --help
will also tell you more.
Quoting from yum
:
Yum command has been deprecated, redirecting to '/usr/bin/dnf '.
See 'man dnf' and 'man yum2dnf' for more information.
To transfer transaction metadata from yum to DNF, run:
'dnf install python-dnf-plugins-extras-migrate && dnf-2 migrate'
You need to give some command
usage: dnf [options] COMMAND
EDIT: dnf
has its config file here: /etc/dnf/dnf.conf, and I recommend adding fastestmirror=1
at the end of the file.
EDIT2: I thought this might be helpful as well: dnf uses the .repo-files located in /etc/yum.repos.d/ (as of Fedora 22/23).

@baroquequest: Assuming you are talking about Fedora22, I took the liberty of adding it as tag to your question.
