+
+Where metadata comes from
+===
+
+The metadata used to specify what hardware a piece of software requires, what ages of user it is suitable 
for, and factors which contribute to how safe it might be to install, all come from the metainfo file for 
that software.
+
+The metainfo file format is specified in the [AppStream 
specification](https://www.freedesktop.org/software/appstream/docs/).
+
+What happens if metadata is missing
+===
+
+If some metadata is missing for an application, GNOME Software can only guess what it might be, and hence 
can’t present much information in its interfaces. The guesses GNOME Software makes are based on the fact that 
most software is designed for desktop computers.
+
+**You can help improve the metadata for an application!** See below for a guide on how to do that.
