@alv67 and/or @gteti would you please give it a look and let me know if you agree to merge?

I added a new HOWTO to https://arneis.readthedocs.io/

The new page which you can preview at https://arneis--350.org.readthedocs.build/en/350/howto/howto-create-landing-page-netlify.html contains some TODO but I believe is already OK for public consumption.
