Your public URL does not change. ## From the dashboard In the [dashboard](https://unfurl.pub/dashboard), select the document you want to update. Drag a fresh `.html` file onto the drop zone. This appends a version. Add a version note when the UI offers it — short strings help you scan history later. ## From MCP (`publish_document`) Include the **`document_id`** you received when the document was first created: ```text Example theme={null} publish_document document_id: "your-uuid-here" title: "Same title or an updated one" html: "..." note: "Fixed table totals" ``` Omit `document_id` only when you intend to create a **new** document with a **new** link. ## Same link, new content Recipients refresh the same URL and see the latest **published** version. You do not re-send a different address. **Version notes:** Use the present tense and a noun phrase — "Add ROI section", "Legal wording v2". Avoid empty notes; future you will thank you.
