 ```
 
 With this setting, if a key is missing, `autorestic` will crash instead of generating a new key and updating your config file.
+
+## Automatic Backend Initialization
+
+`autorestic` is able to automatically initialize backends for you. This is done by setting `init: true` in the config for a given backend. For example:
+
+```yaml | .autorestic.yml
+backend:
+  foo:
+    type: ...
+    path: ...
+    init: true
+```
+
+When you set `init: true` on a backend config, `autorestic` will automatically initialize the underlying `restic` repository that powers the backend if it's not already initialized. In practice, this means that the backend will be initialized the first time it is being backed up to.
+
+This option is helpful in cases where you want to automate the configuration of `autorestic`. This means that instead of running `autorestic exec init -b ...` manually when you create a new backend, you can let `autorestic` initialize it for you.
