 Usage
 ======
 
-To use, run either the run_pylint_linting.sh or run_flake8_linting.sh scripts
+It is recommended to run ``pre-commit install`` in a terminal under the main ``DESC`` directory.
 
-These will generate a pylint.output file, or flake8_errors.ouput and flake8_summary.output files.
+Then anytime you commit with ``git commit`` the linting suite will run automatically.
 
-Currently, black is still ran through GitHub actions.
+To manually generate a linting report you need to execute the shell script ``run_flake8_linting.sh`` by typing ``sh run_flake8_linting.sh`` in a terminal from the ``devtools`` directory.
 
-Most formatting-level errors are being suppressed; errors that touch the code logic are primarily the ones being raised.
+This will generate the ``flake8_errors.output`` and ``flake8_summary.output`` files.

 Currently, error messages about whitespace and indenting that black does not care about have been suppressed.
 These will be fixed in a future cleanup branch.
 More errors can be added to the [flake8] section of settings.cfg after "ignore=", separated by commas.

-Pylint:
--------
-Currently several classes of error are being suppressed, mostly to do with preferring encapsulating behavior into simpler classes and modules.
-To disable certain classes of error message, go to the [MESSAGES] section of pylinrc, and add the error to "disable=" separated by commas.
-Additionally, several very minor errors are being suppressed to be fixed in a future cleanup branch.
