 # epanet python package
 
-A slender, auto-generated python wrapper around owa:epanet hydraulic network analysis toolkit. This package uses SWIG and scikit-build to generate python bindings into the C library. The goal of this package is to establish basic python support for the toolkit, rather than present a "pythonic" interface. More abstractions can be built atop this package to further abstract the API, but the set of functions here is meant to (as closely as practical) mirror the well-known and established C API.
+A slender, auto-generated python wrapper around the owa:epanet hydraulic network analysis toolkit. This package uses SWIG and scikit-build to generate python bindings into the C library.

More abstractions can be built atop this package to further abstract the API, but the set of functions here is meant to (as closely as practical) mirror the well-known and established C API.
 
 Where possible, SWIG has been configured to throw warnings/exceptions instead of using the customary EPANET return integer value for success-checking. Also any output (pointer) parameters from the C API have been re-routed to return values. In these cases, the return tuple from the Python API will contain the values desired.
 
 
 ## Building the libraries
 
-Ensure the EPANET subproject is populated by running `git submodule update --init` (if necessary) and running the following commands (on Windows skip the line `./script/clean.sh`). The following method uses `scikit-build` to invoke `cmake` for compiling and linking the shared libaries, and builds a python wheel.

 Test your builds using the following commands.
 ```
-cd test && pipenv install ../dist/*.whl && pipenv run python -c 'from epanet import toolkit; print(toolkit.__dict__)'
