LGTM! Although, I wonder if we should move contributing.md from main ludwig to ludwig docs, and then point to the ludwig docs contributing.md from the main ludwig repo. What do you think?

Nice!

@arnavgarg1 Before I merge, let us discuss. I kept it in the code repository using the logic that contributing is closer to code than documentation. I am not sure which is the best way; what is the reason for your recommendation that it be kept in the documentation repository? Thanks.

Btw, you will also need to edit mkdocs.yaml to remove the contributing guide from the website index (it'll make sense once you take a look at the file in the repo)!

@alexsherstinsky got it! I think that's reasonable actually, we can leave it in the main Ludwig repo.

@arnavgarg1 I thought that I did that -- could you please double check to make sure I did not miss it? Thanks!

[arnavgarg1]

Oh I see it now, sorry about that!

@arnavgarg1 Not at all -- really appreciate doing the rechecking. Is there a way to view the "staged" content of the pull request, before I merge? Something like Netlify perhaps? Thanks!
