# Update reference files

When you initially open Flood Modeller, you may receive a pop-up asking if you would like to update references. This is to check for, download and implement the latest reference files for the online mapping services. This also updates references to the links that take you from the software to pages within this knowledgebase. If you selected **No** to the pop-up, or would like to re-check for any updated references, this can be done at any time.

To check for updated references:

1. Navigate to the **Start** tab and click on **Help** on the left-hand-side.
2. Click the **Update references** button.
3. Restart Flood Modeller for these changes to take effect.
