# Check for Updates
Building Information Model Climate Action Tool (bimCAT) automatically checks for updates on Revit startup. If an update is found, the plugin displays the following window.
To install:
* Follow the URL to the download location and download the plugin installer.
* Close Revit.
* Double-click on the installer to update the plugin.
The same check could be performed manually through the **Help > Check for Updates** command in the Building Information Model Climate Action Tool (bimCAT) ribbon.
If an update was found, you'll see the same prompt as above.
If not, you'll be informed that bimCAT is up to date.
