+# Conditional Workflow Sample
+
+This sample demonstrates control flow with conditions:
+- If/else branching
+- Nested conditions
+
+## Files
+
+- `workflow.yaml` - The workflow definition
+- `main.py` - Python code to execute the workflow
+
+## Running
+
+```bash
+python main.py
+```
+
+## What It Does
+
+1. Takes a user's age as input
+2. Uses conditions to determine an age category
+3. Sends appropriate messages based on the category
