   :target: https://heroku.com/deploy?template=https://github.com/numbas/numbas-lti-provider/tree/heroku

You'll be prompted to create an account, if necessary, and then click :guilabel:`Deploy app`.
Once the app is deployed, it's ready to use: click the :guilabel:`View` button to begin the web-based setup.

This service is unlikely to be adequate for use with large numbers of students.
Heroku offers a paid service which can scale up to meet demand, but make sure to check its costs and terms carefully.
