  <title>What are GNOME Shell extensions?</title>
  
  <p>GNOME Shell extensions allow customizing the default GNOME Shell interface
  and its parts, such as window management and application launching.</p>
  
  <p>Each GNOME Shell extension is identified by a unique identifier, the uuid.
  The uuid is also used for the name of the directory where an extension is
  installed. You can either install the extension per-user in
  <file>~/.local/share/gnome-shell/extensions/&lt;uuid&gt;</file>, or
  machine-wide in
  <file>/usr/share/gnome-shell/extensions/&lt;uuid&gt;</file>.</p>
  
  <p>To view installed extensions, you can use <app>Looking Glass</app>, GNOME
  Shell's integrated debugger and inspector tool.</p>
