 The array API will offer the following syntax for data interchange:
 
-1. A ``from_dlpack(x, ...)`` function, which accepts any (array) object with
+1. A :func:`~array_api.from_dlpack()` function, which accepts any (array) object with
    the two DLPack methods implemented (see below) and uses them to construct
-   a new array containing the data from ``x``.
-2. ``__dlpack__`` and ``__dlpack_device__`` methods on the
-   array object, which will be called from within ``from_dlpack``, to query
+   a new array containing the data from the input array.
+2. :meth:`~array_api.array.__dlpack__` and :meth:`~array_api.array.__dlpack_device__` methods on the
+   array object, which will be called from within :func:`~array_api.from_dlpack`, to query
    what device the array is on (may be needed to pass in the correct
    stream, e.g. in the case of multiple GPUs) and to access the data.
