# Retiring an Ingested Document

Duplicate content may be ingested from different sources. But you can remove (delete) documents from the pipeline using the **Retire Knowledge Documents** command. Retired documents will still exist in your data source.

To retire content from a particular source:

1. Navigate to **Settings > Data Sources** in the Aisera Admin UI.
2. Choose a Data Source with documents that you want to retire.
3. At the top of the **Data Source Details** window, click on the **Retire Knowledge Documents** button.<br>

   <div data-gb-custom-block data-tag="hint" data-style="info" class="hint hint-info"><p>This icon will not appear if you have not ingested any knowledge articles</p></div>
