# kde-redhat.org > The RHEL & Fedora field guide. Tested-on-real-systems tutorials for the Red Hat family of Linux distributions (RHEL, AlmaLinux, Rocky Linux, CentOS Stream, Fedora), the KDE Plasma desktop on Fedora, and Linux certification (RHCSA and friends). Every guide states the distro version, kernel and test date, shows expected output for every command, and includes a "If this fails" section. SELinux and firewalld are always handled properly, never disabled as a shortcut. ## About this domain - [The kde-redhat project, 2003-2013](https://kde-redhat.org/origem/): this domain originally hosted the kde-redhat packaging project, which shipped up-to-date KDE packages for Red Hat Linux, Fedora and RHEL for a decade and preceded Fedora's KDE SIG. The page preserves that history. The current site is run by new custodians of the domain, publishing new field guides in the same spirit. ## Guides Guides are listed on the home page as they are published.
