Collate reads descriptions from `manifest.json` by default. If you also provide `catalog.json`, the catalog descriptions take priority. | Files provided | Descriptions used | | -------------------------------- | --------------------------------- | | `manifest.json` only | Descriptions from `manifest.json` | | `manifest.json` + `catalog.json` | Descriptions from `catalog.json` | ## Override Existing Descriptions By default, Collate only fills in descriptions for tables and columns that don't have one yet — it won't touch descriptions you've already written in Collate. Turn on the **Update Descriptions** toggle in the dbt ingestion configuration if you want dbt to be the single source of truth. When enabled, dbt descriptions overwrite any existing descriptions in Collate. Update Descriptions toggle
