-# What is chrome://settings?
+# Deprecation
+
+This doc refers to "options", the soon-to-be-deprecated version of
+chrome://settings being replaced by Material Design Settings.
+
+We encourage any new features and bug fixes to be contributed to MD Settings,
+which can be found in the /settings/ directories (as opposed to the /options/
+directories).
+
+We won't block high-priority updates to Options, especially for bug fixes or
+urgent features, but know that your team will also responsible for implementing
+those new features in MD Settings.

Done.

+See: https://www.chromium.org/developers/updating-webui-for-material-design
+
+Note: As the soft launch begins, chrome://settings may start surfacing the
+Material Design settings page. The deprecated "options" page will be available
+during this time at chrome://settings-frame, but will eventually be removed.
+
+# Outdated
+
+The remainder of this doc has not been substantially updated in some time, but
+is generally correct. Contact /options/ OWNERS if you have questions, but see
+the deprecation notice above.
