Problem

We have

• https://matplotlib.org/stable/#install thought as short instructions on the landing page
• https://matplotlib.org/stable/install/index.html as the complete install guide

They are mostly fine.

Issues:

• There'shttps://matplotlib.org/stable/users/getting_started/#installation-quick-start, which seems a bit outdated. I'm not sure whether this is still needed, and I haven't found a link to it from any page belowhttps://matplotlib.org/stable/. However the landing pagehttps://matplotlib.org/ links to it from the "Getting started" icon.
  Suggested improvement: Minimally replace the install instructions at byhttps://matplotlib.org/stable/users/getting_started/#installation-quick-start, a link tohttps://matplotlib.org/stable/#install. Alternatively, investigate to removehttps://matplotlib.org/stable/users/getting_started/ completely.

• AFAICS there is no obvious link fromhttps://matplotlib.org/ to any installation information. The "documentation" icon connects to the version-specific landing pagehttps://matplotlib.org/stable/
  Suggested improvement: It may be difficult to resolve this duality of global landing page and version-specific landing page. Minmally, move the "Documentation" icon to the very right in the icon row. It's the most general one. The other icons are direct links to sub-topics.

• https://matplotlib.org/stable/install/index.html as the complete install guide could/should get more information on package managers. We only focus on the packages wheel/conda, but don't mention the package managers. While not strictly our business, it may be a good service to our users to add 1-2 sentences on the package managers, because that's the interface they will use.
