 ---------------------------------------
 
 The Pyramid cookiecutter includes configuration defaults for ``pytest`` and test coverage.
-These configuration optionas are defined in  stanzas of the ``pyroject.toml`` file.
+The configuration for ``pytest`` is in the ``pyroject.toml`` file in the ``tool.pytest.ini_options`` stanza.
