+
+#### Credentials
+To get credentials, go to this link here: https://github.com/ovh/php-ovh#supported-endpoints, pick the right endpoint and go to the right **/createApp/** application credentials page.
+The application needs to have the following rights:
+- GET /ip
+- GET /ip/*
+- POST /ip/*
+- DELETE /ip/*
+
+Don't forget to set the right endpoint region in the config file.
