# Getting a 🦖 trex file

When the extension server is started open in the browser: `https://{your-host}/trex`. Here you can download it. You can share the URL to your users to distribute:

There will be two download buttons if the extension supports both a Viz extension and a dashboard extension. For extensions with modules, such as ShowMeMore, when the user downloads the viz extension trex, a Zip file containing all the visualizations bundled with the license.
