+## Debugging
+
+The debugging process for DuckDB extensions is not an easy job. For Netquack, we have created a log file in the current directory. The log file is named `netquack.log` and contains all the logs for the extension. You can use this file to debug your code.

 ## Roadmap 🗺️
 
 - [ ] Create a `TableFunction` for `extract_query_parameters` that return each key-value pair as a row.
