 - `tox -e py311-test-instrumentation-aiopg` to e.g. run the aiopg instrumentation unit tests under a specific
   Python version
 - `tox -e spellcheck` to run a spellcheck on all the code
-- `tox -e lint` to run lint checks on all code
+- `tox -e lint-some-package` to run lint checks on `some-package`
 
 `black` and `isort` are executed when `tox -e lint` is run. The reported errors can be tedious to fix manually.
 An easier way to do so is:
 
-1. Run `.tox/lint/bin/black .`
-2. Run `.tox/lint/bin/isort .`
+1. Run `.tox/lint-some-package/bin/black .`
