# Saving Changes As soon as you make any change to a Flow in the Contextual Flow Editor, you'll see the red Save button in the upper right of the screen activate. Each time you save a Flow you will get a new Flow version automatically. This makes it very simple to revert changes. Remember, if you do save changes on a Flow you need to restart the Agent with the new Flow version in order for those changes to take effect. You can always test your changes in the Flow editor before deploying. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.contextual.io/documentation-and-resources/components-and-data/flows/node-red-flow-editor/saving-changes.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
