+## Custom metrics
+It is possible to retrieve custom prometheus metrics for a mssql instance using the optional `query_config_path` parameter.
+
+This parameter should point to a YAML config file defined [here](https://github.com/burningalchemist/sql_exporter#collectors). If it does, it will use the new config to query your mssql instance and create whatever metrics are defined.
+If you want additional metrics on top of the default provided ones, the default config should be used as a base.
+
+The default config file used by this integration is as follows:
