+For now moment, the deployment is not automatic. Instead, after submitting,
+visit the [Cloud Build triggers list](https://console.cloud.google.com/cloud-build/triggers?project=go-discovery),
+find the one named “Redeploy-go-dev-on-website-commit”, which should say “Disabled” in the status column,
+and then click “RUN”.
 
 ## Commands
 
 - Running the server: `go run ./cmd/frontend`
-- Pushing to staging: `git push -f origin HEAD:staging`
