something went wrong here - this PR changes the README back to the old one and deletes the 2_33 version of the docs.

[bob-carpenter]

Sorry about that. I could use some help with the new docs organization. As usual, it took me about 5 minutes to write the text and then an hour wrestling with GitHub and our build process.

closing this, will add changes to 2 .qmd files in a new branch/PR
