Thanks for the contribution. Before we do a deep review, we have a few questions about the content. It might be easier to create a new issue where we can work out what guides to include and what they look like.

My initial questions are:

• Is it possible to run the Portkey system locally instead of using a remote service? This way users can try it out without giving their API key to a third party.
  • If not, would you mind if we put a warning on the part where they share their API key?
• Can you provide some stats on the platform's popularity? See our contrib guide, but we are only accepting contributions for widely adopted platforms, with some exceptions for technical novelty. Public numbers are fine.
• Can you ensure the guide is focused on a single topic (e.g. "using a compatible interface" is one topic, "observability with portkey" is another)
  • Focused content is more useful to users, and it will help us review each guide on its own merits.

We also have a template you can use now, it includes some authoring guidelines. And you'll need to rebase your change to HEAD so you pick up the latest GH actions.
