+Backups of the following program settings/profiles/folders are possible:  
+### System
+* aura
+* bitlbee
+* git
+* mail/ mailman
+* mariadb
+* /var/log
+* /var/log/journal
+* websites
 
+### User

+## Requirements
+At the moment crypted-backups only supports [xz](http://tukaani.org/xz/) compression.  
+
+## Configuration
+Crypted-backups uses two forms of configuration files. One for system-wide services and one for user services.  
+
+### System
+The configuration file for system services can be found in */etc/crypted-backups* and is well documented.
+
+### User
+The configuration file for user services is read from *$HOME/.config/crypted-backups*. 
+Make sure to copy and modify one from your system skeleton folder (**/etc/skel/.crypted-backups**).
+
+## TODO
+* Using [pixz](https://github.com/vasi/pixz)
+* Using [rsync](https://rsync.samba.org/) for backup mirroring
+
+## License
+Crypted-backups is licensed under the GPLv3.
