Thanks for making a start on this @SahilWMI and sorry for the long delay in getting back to you, we've been somewhat swamped in all the amazing contributions coming in through Hacktoberfest!

You do not need to add all the front-matter (the bits above on-boarding) on this document.

You should also create it in /docs/onboarding/onboarding.rst rather than retaining the structure from the old site.

Please see the work others have done in recently merged PRs for how to use the link files where you've used URLs. Most of them now exist in the /links directory so you can just grab the references there (please read the documentation in the issue about using links, where it explains how they work). This also means you can clean up the old link macros at the bottom of the page, too! 🥳

Let me know if you get stuck with any of this, and sorry again for the delay in reviewing, we're trying to get on top of it!

Whoops, forgot to switch to Request Changes 😊
