+The context that the Router will analyze to make routing decisions. This is the input data that gets evaluated against your route descriptions. It can be:

-- Specify routing criteria for each target block
-- Exclude certain blocks from being considered as routing targets
+- **Route Title**: A name for the route (e.g., "Sales", "Support", "Technical")
+- **Route Description**: A clear description of when this route should be selected (e.g., "Route here when the query is about pricing, purchasing, or sales inquiries")

+Each route you add creates a **separate output port** on the Router block. Connect each port to the appropriate downstream block for that route.

 ## Example Use Cases
 
 **Customer Support Triage** - Route tickets to specialized departments

 ## Best Practices
 
-- **Provide clear target descriptions**: Help the Router understand when to select each destination with specific, detailed descriptions
-- **Use specific routing criteria**: Define clear conditions and examples for each path to improve accuracy
-- **Implement fallback paths**: Connect a default destination for when no specific path is appropriate
-- **Test with diverse inputs**: Ensure the Router handles various input types, edge cases, and unexpected content
-- **Monitor routing performance**: Review routing decisions regularly and refine criteria based on actual usage patterns
-- **Choose appropriate models**: Use models with strong reasoning capabilities for complex routing decisions
+- **Write clear route descriptions**: Each route description should clearly explain when that route should be selected. Be specific about the criteria.
+- **Make routes mutually exclusive**: When possible, ensure route descriptions don't overlap to prevent ambiguous routing decisions.
+- **Include an error/fallback route**: Add a catch-all route for unexpected inputs that don't match other routes.
+- **Use descriptive route titles**: Route titles appear in the workflow canvas, so make them meaningful for readability.
+- **Test with diverse inputs**: Ensure the Router handles various input types, edge cases, and unexpected content.
