 ## Roadmap 🗺️
 
+- [ ] Create a version function `SELECT * from netquack_version();`
 - [ ] Create a `TableFunction` for `extract_query_parameters` that return each key-value pair as a row.
 - [ ] Save Tranco data as Parquet
 - [ ] Create Rank category for Tranco ( `top1k` , `top5k`, `top10k`, `top100k`, `top500k`, `top1m` )
