+= Vulkan Roadmap and Feature Descriptions
+
+This component includes the Vulkan Roadmap, the Vulkan 2022 Profile Roadmap,
+and all published extension feature descriptions.
+
+When a Vulkan extension is initially proposed, a feature description is
+written outlining the proposed API, from which specification language is
+written.
+Once the extension is published, the initial "proposal", now
+referred to as a "feature description", is retained to act as
+supplementary documentation on that extension.

+== About
+
+link:https://docs.vulkan.org/[This site] gathers together several key Vulkan
+documents including specifications, extension proposals, guides, tutorials
+and samples into a single site.
+This allows searching and cross-linking across documents, to help navigate
+quickly to the information you need for developing Vulkan-based
+applications.
+
+For more information about and resources for using the Vulkan graphics API,
+see the Vulkan developer website at https://vulkan.org .
+
+This build of the site includes the Vulkan {SPECREVISION} API specification
+{APITITLE}, generated on {SPECDATE} {SPECREMARK}.
+
+
+== Navigation
+
+The site is organized in "components" (Antora terminology for
+specifications and other documents), each containing many "pages"
+(Antora terminology for a chapter of a specification, or other distinct
+piece of content for other components).
+
+The left navigation sidebar links to pages in the current component.
+
+The right navigation sidebar links to sections in the current page.
+
+The bottom-left button switches between components.
+
+The top navigation bar contains a text searchbox.
+If the "In this component" box is checked, search will be
+restricted to the current component.
+Otherwise, all components of the site are searched.
+
+
+== Site Information
+
+link:https://docs.vulkan.org/[This site] is generated using the
+link:https://docs.antora.org/[Antora] static site generator.
+
+If you need to report a problem or build the site yourself, start with the

+GitHub.
