Provide a llms.txt file

[CaiJingLong]

See the https://llmstxt.org/
We can improve the experience of llm when accessing docs.

Yes 100000%. We were looking to get this created last week but didn't have enough time!

@lavinigam-gcp if you have time!

PR #78 might suffice

[koverholt]

@lavinigam-gcp, if you catch me up on the llms.txt work you were doing a couple of weeks ago I can also help push that as a followup to #78.

Yes, Alan made a PR #78 and i approve it. We can merge that. Although, we need to think about if we want to keep it at root folder? Feel free to review #78

[lavinigam-gcp]

Merged, we have the llms.txt in the root now! Closing the issue.
