+## Status
+
+This library is still in development, so expect missing functionality.
+If there's anything you would like to see added, feel free to
+[open an issue](https://github.com/unfoldml/ms-graph-api/issues/new), or even better contribute some code.
+In general, since the API surface is quite large, features will be added to this library on a need basis.
+
+## Evolution of the library
+
+Some breaking changes might also be introduced as the library matures.
+
+We adhere to a simplified version of the [Package Versioning Policy](https://pvp.haskell.org/): breaking changes are signaled by increasing the major version number (e.g. 0.x -> 1.x ).
