+### Modifications by cseitz

+- Disabled functionality to overwrite config files. You will need to specifiy restic repo keys manually.
+
 ### 💭 Why / What?
 
 Autorestic is a wrapper around the amazing [restic](https://restic.net/). While being amazing the restic cli can be a bit overwhelming and difficult to manage if you have many different locations that you want to backup to multiple locations. This utility is aimed at making this easier 🙂.
