 ```bash
 bin/yaml-migrate process -c config.yaml -v
 ```

+
+```
+bin/yaml-migrate process -c config.yaml -v -f m_replace.yaml
+```
+
+Run it in the context of a Bolt installation: 
+
+```
+vendor/bobdenotter/yaml-migrations/bin/yaml-migrate process -c vendor/bolt/core/yaml-migrations/config.yaml -v
+````
+
