+Implementation of the NEP 47 (adopting the array API standard)
+--------------------------------------------------------------
+
+An initial implementation of `NEP 47`_ (adoption the array API standard) has
+been added as ``numpy.array_api``. The implementation is experimental and will
+issue a UserWarning on import, as the `array API standard
+<https://data-apis.org/array-api/latest/index.html>`_ is still in draft state.
+``numpy.array_api`` is a conforming implementation of the array API standard,
+which is also minimal, meaning that only those functions and behaviors that
+are required by the standard are implemented (see the NEP for more info).
+Libraries wishing to make use of the array API standard are encouraged to use
+``numpy.array_api`` to check that they are only using functionality that is
+guaranteed to be present in standard conforming implementations.
