# GNOME Shell GNOME Shell provides core user interface functions for the GNOME desktop, like switching to windows and launching applications. GNOME Shell takes advantage of the capabilities of modern graphics hardware and introduces innovative user interface concepts to provide a visually attractive and easy to use experience. For more information about GNOME Shell, including instructions on how to build GNOME Shell from source and how to get involved with the project, see the [project wiki][project-wiki]. Bugs should be reported to the GNOME [bug tracking system][bug-tracker]. Please refer to the [*Schedule* wiki page][schedule] to see the supported versions. ## Contributing To contribute, open merge requests at https://gitlab.gnome.org/GNOME/gnome-shell.
