+### Testing DNF5 obsoletes DNF
+
+Optionally you can install DNF5 from these COPR repositories[^dnf5-testing][^dnf5-testing-nightly]. The packages are build using the copr option `--rpmbuilds-with dnf5_obsoletes_dnf`. By installing these packages DNF5 will be the default package manager in your system. You will still be able to use DNF running `dnf4`.
+
+Packages from `dnf5-testing` are versioned following Fedora release pace and are updated every two weeks. Packages from `dnf5-testing-nightly` are built nightly.
