+# The step above creates a new Neon branch.
+# You may want to do something with the new branch, such as run migrations, run tests
+# on it, or send the connection details to a hosting platform environment.
+# The branch DATABASE_URL is available to you via:
+# "${{ steps.create_neon_branch.outputs.db_url_with_pooler }}".
+# It's important you don't log the DATABASE_URL as output as it contains a username and
+# password for your database.
+# For example, you can uncomment the lines below to run a database migration command:
+#      - name: Run Migrations
+#        run: npm run db:migrate
+#        env:
+#          # to use pooled connection
+#          DATABASE_URL: "${{ steps.create_neon_branch.outputs.db_url_with_pooler }}"
+#          # OR to use unpooled connection
