-All Debian based systems use
-http://en.wikipedia.org/wiki/Advanced_Packaging_Tool[APT] as package
-management tool. The list of repositories is defined in
-`/etc/apt/sources.list` and `.list` files found inside
-`/etc/apt/sources.d/`. Updates can be installed directly using
-`apt-get`, or via the GUI.
-
-Apt `sources.list` files list one package repository per line, with
-the most preferred source listed first. Empty lines are ignored, and a
-`#` character anywhere on a line marks the remainder of that line as a
-comment. The information available from the configured sources is
-acquired by `apt-get update`.
+{pve} uses http://en.wikipedia.org/wiki/Advanced_Packaging_Tool[APT] as its
+package management tool like any other Debian-based system.
+
+Repositories in {pve}
+~~~~~~~~~~~~~~~~~~~~~
+
+Repositories are a collection of software packages, they can be used to install
+new software, but are also important to get new updates.
+
+NOTE: You need valid Debian and Proxmox repositories to get the latest
+security updates, bug fixes and new features.
+
+APT Repositories are defined in the file `/etc/apt/sources.list` and in `.list`
+files placed in `/etc/apt/sources.list.d/`.
+
+Repository Management
+^^^^^^^^^^^^^^^^^^^^^
+
+[thumbnail="screenshot/gui-node-repositories.png"]
+
+Since Proxmox VE 7.0 you can check the repository state in the web interface.
+The node summary panel shows a high level status overview, while the separate
+'Repository' panel shows in-depth status and list of all configured
+repositories.
+
+Basic repository management, for example, activating or deactivating a
+repository, is also supported.
+
+Sources.list
+^^^^^^^^^^^^
+
+In a `sources.list` file, each line defines a package repository. The preferred
+source must come first. Empty lines are ignored. A `#` character anywhere on a
+line marks the remainder of that line as a comment. The available packages from
+a repository are acquired by running `apt-get update`. Updates can be installed
+directly using `apt-get`, or via the GUI (Node -> Updates).
