+## duplicity-backup.sh IS NOT duplicity
+
+It is only a wrapper script for duplicity written in bash!
+
+This means the following:
+
+* You need to install and configure duplicity before using duplicity-backup.sh
+* [The official documentation of duplicity](http://duplicity.nongnu.org/duplicity.1.html) is relevant to duplicity-backup.sh too. Virtually any option supported by duplicity can be specified in the config file of duplicity-backup.sh. See the `STATIC_OPTIONS`, `CLEAN_UP_TYPE` and `CLEAN_UP_VARIABLE` parameters in particular.
+* Before asking something about duplicity-backup.sh, ensure that your question isn’t actually concerning duplicity ;)
