@ -4,7 +4,7 @@ Like most modern Linux distributions, Fedora uses a _package management_ system.
Each application or component is defined as a _package_. When the package is installed, all code, configuration, and other files are deployed on the system.
IMPORTANT: A package is not necessarily the same as an application. Some applications can be shipped as several packages. Moreover, shared code (libraries) in Linux is normally shipped as separate packages, while in other systems applications often ship their own versions of required libraries and install them if necessary.

Moreover, shared code (libraries) in Linux is normally shipped as separate packages, while in other systems applications often ship their own versions of required libraries and install them if necessary.
The package management tools track which files on your Fedora installation belong to each package; normally, every file that is installed in the `/usr` tree as well as most configuration files under `/etc` are installed by one of the packages. When installing a package, the package management system verifies its integrity; if any files are missing or corrupted, the package is not installed.

In fact, for most Linux distributions, including Fedora, all of the system installation except the earliest part is performed by installing various packages. Security updates and upgrades to a next release are performed entirely by package management tools.
Fedora's package management system uses the http://rpm.org[RPM] package format. The application that manages packages in Fedora (since version 22) is https://fedoraproject.org/wiki/DNF[DNF]. Graphical package management is provided by the Gnome Software utility. For automatic updates, Fedora uses the PackageKit utility.

Graphical package management is provided by the Gnome Software utility. For automatic updates, Fedora uses the PackageKit utility. Command-line and graphical tools provide the same results.
To get packages, DNF uses _repositories_. A repository is an organized collection of packages. Repositories can be kept on any data media; notably, the Fedora installation image contains a repository. However, most up-to-date repositories are normally maintained online.
Each Fedora release has an official _fedora_ repository and an _updates_ repository (which contains critical updates since the release). In these repositories, you can find most common Linux open-source software. You can also install packages from other repositories, not maintained by the Fedora project and known as _third-party repositories_.
Most of the time, it is best practice to install software on your Linux system using only the package management system (DNF). In this case, packages are installed in the most reliable way and automatic updates can be provided.
Most of the time, it is best practice to install software on your Fedora Linux system using only the Fedora package management system. In this case, packages are installed in the most reliable way and automatic updates can be provided.
While many Linux applications can be built and installed from from source code, using such builds can make your system much harder to manage. For example, automatic updates to system packages (especially when updating to the next release) might impact an application that was installed from source. And, of course, no automatic security updates are available for the application.

The most commonly used third-party repository is https://rpmfusion.org/[RPM Fusion]. It provides packages that can not be included in Fedora because of US software patents or other similar reasons. Among other things, RPM Fusion provides packages necessary for viewing media in many common formats. RPM Fusion packages are extensively tested, but they are not supported by the Fedora project.
A set of repositories for Fedora is known as https://copr.fedorainfracloud.org/[Copr]. Developers can provide packages in Copr repositories for software that is not at present included in Fedora. *These packages can be untested.*

Certain non-free applications for Linux, such as Google Chrome or Skype, provide their own repositories for Fedora.
To install software from a third-party repository, you must first _enable_ that repository. Then the packages from the repository become available in the command line and graphical package management tools.
IMPORTANT: if you enable a third-party repository, packages that you did not explicitly select might also be installed from the repository. Do not enable repositories that you do not trust. The Fedora project does not support third-party repositories.
