• do any new files fulfill the naming conventions specified in https://github.com/SUSE/doc-modular/blob/main/templates/README.md?
• article title/structure title: does it have the required length and does it use sentence style capitalization?
• revhistory: is it up-to-date and does it follow the guidelines specified in https://documentation.suse.com/style/current/html/style-guide-db/sec-smartdocs.html#sec-revhistory?

Depends on #649 and #655.

Also note: The published docs at https://documentation.suse.com/sle-micro/6.1/ currently link to the 6.0 docs; the intention here is to replace that link with updated 6.1 docs, as is the case for all other 6.1 docs, and to move the listing upwards to vSphere in the config.
