 Some find running linters on every commit to be a nuisance. To avoid the checks triggering during commits, but to check before pushing to the CI, install the hook for pre-push instead::
 
-	tahoe-lafs $ pre-commit install -t pre-push
-	pre-commit installed at .git/hooks/pre-push
-	tahoe-lafs $ git commit -a -m "Add a file that violates flake8"
