## Manage column descriptions

**Deprecation notice**

Support for this feature has been deprecated and is only available if your data sources were onboarded using a legacy [data registration method](https://documentation.immuta.com/saas/configuration/integrations/data-and-integrations/registering-metadata). Column descriptions of data sources onboarded through connections cannot be edited because they are automatically generated based on information from your data platform.
