+### Debugging Locally
+
+To debug the AI runner locally, follow these steps:
+
+1. **Configure launch.json**: Add the following configuration to your `launch.json` file:
+
+   ```json
+   {
+     "version": "0.2.0",
+     "configurations": [
+       {
+         "name": "Python Debugger: LLM",

+         "module": "uvicorn",
+         "args": [
+           "app.main:app",
+           "--log-config",
+           "app/cfg/uvicorn_logging_config.json",
+           "--host",
+           "0.0.0.0",
+           "--port",
+           "8000"
+         ],
+         "env": {
+           "PIPELINE": "text-to-image",

+         }
+       }
+     ]
+   }
+   ```
+
+2. **Set Breakpoints**: Add breakpoints to the code where you wish to pause execution.
+3. **Launch Debugger**: Press `F5` to start the debugger.
