+Sitemaps
+========
+
+Sitemaps_ allows us to inform search engines about URLs that are available for crawling
+and communicate them additional information about each URL of the project:
+
+* when it was last updated,
+* how often it changes,
+* how important it is in relation to other URLs in the site, and
+* what translations are available for a page.
+
+Read the Docs automatically generates a sitemap for each project that hosts
+to improve results when performing a search on these search engines.
+This allow us to prioritize results based on the version number, for example
+to show ``latest`` as the top result followed by ``stable`` and then all the project's
+versions sorted following semver_.
