+CrewAI's power truly shines when combining Crews with Flows to create sophisticated automation pipelines.
+CrewAI flows support logical operators like `or_` and `and_` to combine multiple conditions. This can be used with `@start`, `@listen`, or `@router` decorators to create complex triggering conditions.
+- `or_`: Triggers when any of the specified conditions are met. 
+- `and_`Triggers when all of the specified conditions are met.
