+GNOME Software displays a hardware support tile on the details page for an application. This combines 
information about the hardware requirements of the application, and the hardware capabilities of the 
computer, with the aim of highlighting incompatibilities or missing requirements — or to indicate that the 
application should work correctly with no incompatibilities.
+
+Currently, the code looks at the following hardware. More may be supported in future.
+ * Whether a touchpad, mouse or keyboard is present/needed
+ * Whether a gamepad is needed
+ * The minimum and recommended display size that the app can scale to
+
+It’s not possible to reliably detect whether a gamepad is *present*, as they are often left disconnected due 
to not being needed for normal computer use.
