 This is a small wrapper around NumPy that is compatible with the [Array API

 Note that some of the functionality in this library is backwards incompatible
 with NumPy.
 
+This library also supports CuPy in addition to NumPy.

 Library authors using the Array API may wish to test against `numpy.array_api`
 to ensure they are not using functionality outside of the standard, but prefer
 this implementation for end users who use NumPy arrays.
