+## CI usage
+
+We use a github action to perform API database updates.
+
+We have three [environments](https://docs.github.com/en/actions/deployment/targeting-different-environments/using-environments-for-deployment) to configure the databases and credentials used for an API database update.
+
+The `dev` environment can used on any branch. The `staging` and `production` environments can only be used on the `main` branch.
+
+When an action attempts to use the `production` environment, specific people or teams specified in this repo's settings must approve the action run's access of environment.
