The diff of Install.rst in not very helpful. It's probably easier to compare the online versions:

• Current install guide: https://sundials.readthedocs.io/en/latest/sundials/Install_link.html
• New install guide: https://sundials--637.org.readthedocs.build/en/637/sundials/Install_link.html

Just a few minor comments. Quite thorough, and the tables with header/linking info are helpful.
