 :::{note}
 If a page uses a relative image path, it must be relative to the `toc.yml` or `docset.yml` that includes the page rather than relative to the page itself.
 This type of relative path may fail to render when you run a local build, thus it's generally preferable to use an absolute path, for example: `/solutions/images/observability-apm-app-landing.png`.
+
