@kolchfa-aws This PR is ready for review,

I decided not to update the index.md page just yet, as it will cause conflicts with every PR, until all mappings are done. Probably better to do them all at once once this is complete?

Yes, I think the index page can be updated last. It's better not to have merge conflicts :)
