+### Feature flags
+
+[Feature flags](/components/overview/feature-flags/) have been added to the
+clickable, selectable, and expandable variants of tile to improve accessibility
+and changes its visual appearance, not its functionality. For more code-specific
+feature flag information, refer to the
+[@carbon/react](https://react.carbondesignsystem.com/?path=/docs/experimental-feature-flags-tile--overview)
+framework.
+
+- The `enable-experimental-tile-contrast` flag adds a border to the tile with
+  improved contrast for accessibility and to visually indicate they are
+  operable.
+- The `enable-v12-tile-default-icons` flag enables the rendering of default
+  icons on the clickable variant of tile like the ArrowRight icon for navigation
+  or Error icon when it is disabled if the user hasn't configured a different
+  icon already.
+- The `enable-v12-tile-default-icons` flag enables the rendering of default
+  icons on the clickable variant of a tile, such as the ArrowRight icon for
+  navigation or the Error icon when the tile is disabled. If the user hasn't
+  configured a different icon, these defaults will be used.
+- The `enable-v12-tile-radio-icons` flag changes RadioTile to use radio button
+  icons instead of a checkmark icons.
