I’d like to include a link on the home page to a site map of the website.
This would be one way to comply with WCAG 2.1
2.4.5 Multiple Ways
Multiple ways are available to find other web pages on the site - at least two of: a list of related pages, table of contents, site map, site search, or list of all available pages.
I know that we can generate an XML site map, but I have no idea how we might use that as an index page.
