+@item import
+Generate a @dfn{home environment} from the packages in the default
+profile and configuration files found in the user's home directory.  The
+configuration files will be copied to the specified directory.  Note
+that not every home service that exists is supported (@pxref{Home
+Services}).
+
+@example
+$ guix home import ~/guix-config
+;; This "home-environment" file can be passed to 'guix home reconfigure'
+;; to reproduce the content of your profile.  This is "symbolic": it only
+;; specifies package names.  To reproduce the exact same profile, you also
+;; need to capture the channels being used, as returned by "guix describe".
+;; See the "Replicating Guix" section in the manual.
