 A note on naming
 ================
 
 For the purposes of uniformity and easy of discovery alongside the reference
-implementation, we use the same module name as `merkle-tree-stream`_. This may
-cause confusion since it is not clear what exactly is referred to when using
-the term "stream" in the context of Python. To be clear, this module provides a
-`Python iterator`_ which appears to match the implementation and meaning of the
-reference implementation.
+implementation, we use the same module name as `merkle-tree-stream`_. However,
+there is currently no stream implemented, only a generator is available. This
+is because the reference implementation of Hypercore 7 makes use of the
+generator only. A `stream`_ implementation may follow.
