• GRASS GIS addons overview generator for entire GitHub (and more?) based on tag "grass-gis-addons"
• Discuss about a 4th edition of "Open Source GIS: A GRASS GIS Approach"

• GRASS GIS manual pages: re-styling and conversion of all pages:
  • convert to markdown
  • using mkdocs (https://www.mkdocs.org/): it provides menus and a search window
