 This allows TypeScript to throw an error if you try to pass `value={new Date()}` to a component using `AdapterDayjs` for instance.
 
-If you run into TypeScript errors such as `DesktopDatePickerProps<Date> error Type 'Date' does not satisfy the constraint 'never'`,
-it is probably because you are not importing the adapter in the same TypeScript project as the rest of your codebase.
-You can fix it by manually importing the adapter in some file of your project as follows:
+If you are not sure your adapter is set up correctly to infer the type of date-related props, you can import the `PickerValidDate` type and check its current value.
+
+If its equal to the format used by your date library, then you don't have to do anything:
