 # Setting up CI
 
-Once you have all the tests passing, you'll need to set up CircleCI to run those tests against your driver. You'll need to add a step to [`./circleci/config.yml`](https://github.com/metabase/metabase/blob/master/.circleci/config.yml) to run tests against your database, then add that step to the "workflows" at the bottom of the config file.
+Once you have all the tests passing, you'll need to set up GitHub Actions to run those tests against your driver. You'll need to add a new job to [`.github/workflows/drivers.yml`](https://github.com/metabase/metabase/blob/master/.github/workflows/drivers.yml) to run tests against your database.
