+## ❓ QA
+
+### My config file was moved?
+
+This happens when autorestic needs to write to the config file. This happend e.g. when we are generating a key for you.
+Unforunately during this process formatting and comments are lost. That is why autorestic will place a copy of your old config next to the one we are writing to.
