 # Run the rule/model passing the data

 ```
 
 The `Parser` class parses the rule/model and creates a graph of nodes. The `Runner` class runs the rule/model using the data passed to the runner. The `data` is a dictionary or a list of dictionaries containing the data that will be used to evaluate the conditions and execute the actions. To see wich data is required for the given rule/model, check the `runner.request_model` property that is a pydantic model used to validate the data.
 
+Optionally you can name the rule by passing the `name` field to the `retrack.Runner` constructor. This is useful to identify the rule when exceptions are raised.
+
 ### Creating a rule/model
 
 A rule is a set of conditions and actions that are executed when the conditions are met. The conditions are evaluated using the data passed to the runner. The actions are executed when the conditions are met.
