+# Info
+
+Displays the config file that autorestic is referring to.
+Useful when you want to quickly see what locations are being backed-up where.
+
+**Pro tip:** if it gets a bit long you can read it more easily with `autorestic info | less` 😉
+
+```bash
+autorestic info
+```
+
+## With a custom file
+
+```bash
+autorestic -c path/to/some/config.yml info
+```
