-For best performance and user experience, it is recommended to run CoLRev natively on Linux or via WSL2 on Windows.
-For testing purposes or macOS, using the pre-configured virtual machine on VirtualBox is feasible, but performance is highly dependent on powerful hardware.

+For best performance and user experience, it is recommended to run CoLRev natively on a machine with Ubuntu 22.04 installed.

+Windows machines can run CoLRev via WSL2 with Ubuntu 22.04 installed.
+Using Ubuntu 22.04 via WSL2 does not provide the default GNOME Desktop Environment (GNOME DE).
+Applications with a GUI such as gitk or VSCode can be run via commands using the CLI provided.

 CoLRev runs natively on **Linux** distributions and the step-by-step instructions apply to Linux systems.
-They are tested for `Ubuntu 22.04.3 LTS <https://ubuntu.com/download/desktop>`__ and `Debian 11.7 “Bullseye” <https://www.debian.org/releases/bullseye/debian-installer/>`__.
-Please note that current Non-LTS versions (22.10, 23.04, 23.10) of Ubuntu and Debian 12 “Bookworm” are not supported due to a change in the handling of the `pip package manager <https://itsfoss.com/install-pipx-ubuntu/>`__.
-Support for newer Linux distributions is scheduled for April 2024 with the next LTS release of Ubuntu.
+They are tested for `Ubuntu 22.04 “Jammy” <https://releases.ubuntu.com/jammy/>`__ and `Debian 11.7 “Bullseye” <https://www.debian.org/releases/bullseye/debian-installer/>`__.
+Please note that newer versions of Ubuntu (22.10, 23.04, 23.10, 24.04) and Debian 12 “Bookworm” are not supported due to a change in the handling of the `pip package manager <https://itsfoss.com/install-pipx-ubuntu/>`__.
 
 The last sections of the setup explain how to setup CoLRev on Windows using the WSL2 and on macOS using a Virtual Machine.
