 Blueprint is a React UI toolkit for the web.
 
-This package contains re-exports of some components from @blueprintjs/datetime v5.x. These "V2" APIs are backwards-compatible with @blueprintjs/datetime2 v0.x. Once you upgrade to Blueprint v5.0, you should migrate your
-imports to reference @blueprintjs/datetime instead:
-
-```diff
-- import { DateInput2 } from "@blueprintjs/datetime2";
-+ import { DateInput } from "@blueprintjs/datetime";

-
-This package also contains next-generation "V3" components which support react-day-picker v8. This means that
-installing @blueprintjs/datetime2 will install multiple versions of react-day-picker (v7.x via @blueprintjs/datetime
-and v8.x as a direct dependency). Note that these two copies of react-day-picker can happily exist together in a single
-JS bundle, and with the help of tree-shaking, you can avoid bundling both if you _only_ use the deprecated "V1" / "V2"
-datetime components or _only_ use the new "V3" APIs.
+This package contains next-generation components for interacting with dates & times.
+
+Compared to the "V1" components in @blueprintjs/datetime, the "V3" components in this package:
+
+-   use [react-day-picker](https://react-day-picker.js.org/) v8 instead of v7 (this unblocks React 18 compatibility)
+-   are easier to internationalize & localize since date-fns is now a dependency (instead of `localeUtils`, you can specify a locale code and we'll automatically load the date-fns locale object)
+
+This package also contains legacy APIs which are re-exported aliases for components from @blueprintjs/datetime v5.x.
+These "V2" names are backwards-compatible with @blueprintjs/datetime2 v0.x.
+
+To migrate to the latest "V3" components, follow the [react-day-picker v8 migration guide](https://github.com/palantir/blueprint/wiki/react-day-picker-8-migration).
+
+Note that @blueprintjs/datetime2 will transitively install multiple versions of react-day-picker.
