 ## Coding conventions
 
-- Use [black](https://github.com/psf/black) code formatter. If you have tox
-  installed, run `tox -e black` to see what changes will be made. You can use
-  `tox -e black-format` to update the code formatting prior to committing.
+- Formatting and linting are incorporated using [ruff](https://docs.astral.sh/ruff/).
+- If you use [pre-commit](https://pre-commit.com/) the checks will run automatically
+  when you commit some changes
+- If you prefer to run the ckecks manually, use `tox -e fix` to run the
+  pre-commit checks for you.
 - Pass pylint
   - exceptions are possible, but you will need to make a good argument
 - Use spaces not tabs for indentation
