+you want to have a Steam library in by either setting this variable in your
+environment or launching Steam with:
+
+@example
+GUIX_SANDBOX_EXTRA_SHARES=/some/other/drive steam
+@end example
+
+This should allow you to select @code{/some/other/drive} in Steam for a game
+library.  This is an experimental feature and just provides a basic way to add
+shares to the container, so please test and report any difficulties or
