+### Umount Module
+---------
+This module represents the last part of the installation, the unmounting of partitions used for the install.  It is also the last place where it is possible to copy files to the target system, thus the best place to copy an installation log.
+
+You can either use the default ```/root/.cache/Calamares/Calamares/Calamares.log``` 
+to copy or if you want to use the full output of ```sudo calamares -d``` to create a log you will need to include a log creation to your launcher script or add it to the used calamares.desktop, example of a launcher script:
+
+```
+#!/bin/sh
+sudo /usr/bin/calamares -d > installation.log 
+```
+Example desktop line:
+```
+Exec=sudo /usr/bin/calamares -d > installation.log
+```
+Set the source and destination path of your install log in umount.conf.
+If you do not wish to use the copy of an install log feature, no action needed, the default settings do not execute the copy of an install log in this module.
