# Update or remove a source

Update or remove a knowledge source in Nuteq from the Knowledge page by replacing a file, deleting a row, or clearing several at once.

In Nuteq, you update a knowledge source when its content changes, and you remove one when it no longer applies. Both actions happen from the Knowledge page, next to the source itself. Updating keeps the source's connections to your agents in place, while removing it deletes the source entirely.

## Before you start

Replace only works for uploaded documents and written text sources, and only once a source shows Ready. Website imports and FAQ sources don't have a Replace option. To update a website, import it again as described in [Add a website](/docs/knowledge/add-a-website); to update an FAQ, edit or delete the question and answer pair directly. Deleting a source removes it right away, with no confirmation step, so double check you've selected the correct row before you click delete.

## Steps

First, open Knowledge from the dashboard. Second, to update a document or text source, click Replace next to it, choose a corrected Markdown or Word file, and click Replace again to confirm. Third, to remove a source, click the trash icon on its row, or check the boxes next to several sources and click Delete Selected to remove them all at once. Fourth, confirm the source no longer appears in the list.

## Best practices

Prefer Replace over deleting and re-adding a source whenever the underlying content just needs a correction, since Replace keeps the source connected to whichever agents already use it. Deleting a source and creating a new one breaks that connection, so you'd have to reconnect it under [Connect knowledge to an agent](/docs/knowledge/connect-knowledge-to-an-agent) afterward. Before deleting several sources at once with Delete Selected, check the list carefully, since the action can't be undone.

## Troubleshooting

If the Replace button doesn't appear next to a source, it's either a website or FAQ source, or it's still uploading or processing; see [Check processing status](/docs/knowledge/check-processing-status) for what each status means. If you delete a source by mistake, add it again the same way you originally created it, then reconnect it to any agent that needs it.
