+## Including VARA in an ETC ISO image
+
+If you want to include VARA in a future EmComm Tools Community image build,
+perform the following in Cubic after the main install script is finished.
+
+1. Change into the `/etc/skel` directory.
+
+2. Copy the WINE backup file created in step 5 using the file copy option
+   in Cubic (i.e. `etc-wine-backup-HOST-YYYYMMDD.tar.gz`).
+
+3. Unpack the backup file. This will create `/etc/skel/.wine32`.
+
+```
+tar -xzf etc-wine-backup-*
+```
+
+4. Delete the backup file on the Cubic session to save on space.
+
+```
+rm etc-wine-backup-*
+```
