Could you please add links to the relevant GCP products we're covering in the guide?

I believe we're referring to:

• GCP Cloud Run - https://cloud.google.com/run
• GCP Cloud Run functions - https://cloud.google.com/functions

Also, I suggest adjust the page titles and metadata as follows:

---
id: gcp-cloud-run
title: Cloud Run
description: Prepare your crawler to run in Cloud Run on Google Cloud Platform.
---

---
id: gcp-cloud-run-functions
title: Cloud Run functions
description: Prepare your crawler to run in Cloud Run functions on Google Cloud Platform.
---

This would result in this structure in the navigation:

- Deploy to Google Cloud
  - Cloud Run functions
  - Cloud Run

Could we please add a brief introduction at the beginning of the pages with the explanation of what service we are going to use and what its purpose is?

In Cloud Run we have "Deploying to Google Cloud Platform" title, could we unify them please?
