 If testing small functions locally that do not require inputs from the main
 Harmony application, it is recommended that you create a Python virtual
-environment via conda, and then install the necessary dependencies for the
+environment, and then install the necessary dependencies for the
 service within that environment via conda and pip then install the pre-commit hooks.
