+# User provided configuration
+You can add user provided configuration files in this folder that can augment
+a loaded config of the same name.
+For example, if you want to change the ***evse_id*** of the
+***connector_1*** in the [config-sil.yaml](../config-sil.yaml) to a value
+specific to your own naming you can achieve this by adding a
+*config-sil.yaml* file in this user-config folder with the following content:
+
+```yaml
+connector_1:
+  config_module:
+    evse_id: "DE*YOURCOMPANY*E12345*1"
+```
+
+This *user-config* does not have to be a *valid* configuration file; it just
+needs to include the keys you want to set/overwrite in the respective config.
