 This repository contains the end-to-end (E2E) test suite for GOV.UK, built using the [Playwright](https://playwright.dev/) framework.
 
-## Running the tests
+## Deployment & Operations
+
+The test suite is automatically deployed to GOV.UK's Kubernetes infrastructure on merge, just like any of our continuously deployed applications. Test traffic therefore originates from one of our three [static NAT gateway IPs](https://eu-west-1.console.aws.amazon.com/vpcconsole/home?region=eu-west-1#NatGateways:sort=tag:Name) (there are no other identifiers, e.g. custom UA string, for test traffic at present).
+
+The test suite is run regularly on weekdays only, [as per the cron schedule](https://github.com/alphagov/govuk-helm-charts/blob/bf5d180b110a16a36af4b4dac2812442a5a298f4/charts/govuk-e2e-tests/values.yaml#L8).
+Failures are not currently reported anywhere. Results can be seen [in Argo](https://argo.eks.production.govuk.digital/applications/cluster-services/govuk-e2e-tests?view=tree&orphaned=false&resource=).
