* feat(backend): add requireKey option to backend

This option will prevent `autorestic` from generating a key and will
cause it to crash instead. This is intended for use cases where you want
to provision the key yourself and don't want `autorestic` to
accidentally generate one for you.

* doc(backend): document requireKey

 ## Types
 
 We restic supports multiple types of backends. See the [full list](/backend/available) for details.
+
+## Avoid Generating Keys
+
+By default, `autorestic` will generate a key for every backend if none is defined. This is done by updating your config file with the key.
+
+In cases where you want to provide the key yourself, you can ensure that `autorestic` doesn't accidentally generate one for you by setting `requireKey: true`.
+
+Example:
+
+```yaml | .autorestic.yml
+version: 2
+
+backends:
+  foo:
+    type: local
+    path: /data/my/backups
+    # Alternatively, you can set the key through the `AUTORESTIC_FOO_RESTIC_PASSWORD` environment variable.
+    key: ... your key here ...
+    requireKey: true
+```
+
+With this setting, if a key is missing, `autorestic` will crash instead of generating a new key and updating your config file.
