+# This GitHub Action demonstrates building a Docker image,
+# pushing it to Docker Hub, and creating a Render build
+# preview with every push to the main branch.
+#
+# This Action requires setting the following secrets:
+#
+# - DOCKERHUB_USERNAME
+# - DOCKERHUB_ACCESS_TOKEN (create in Docker Hub)
+# - RENDER_API_KEY (create from the Account Settings page)
+# - RENDER_SERVICE_ID (the service to create a preview for)
+#
+# You must also set env.DOCKERHUB_REPOSITORY_URL below.
+#
+# Remember to delete previews when you're done with them!
+# You can do this from the Render Dashboard or via the
+# Render API.
