+### Config
+
+If the file `inotify-proxy.yaml` exist in the current working directory, it will be applied.
+
+Example config:
+
+    ---
+    watch:
+      - dir: /tmp/watch1
+      - dir: /tmp/watch2
+    profile: magento2
+
+The profile setting is optional.
+The config loading can be skiped by adding the option `-no-config`.    
+
 ## Supported Profiles
