-You can invoke the pre-commit hook by hand at any time with:
-
-```bash
-pre-commit run

+	
 which should run any autoformatting on your code
 and tell you about any errors it couldn't fix automatically.
 You may also install [black integration](https://github.com/ambv/black#editor-integration)
 into your text editor to format code automatically.
 
+If you have already committed files before setting up the pre-commit
+hook with `pre-commit install`, you can fix everything up using
+`pre-commit run --all-files`.  You need to make the fixing commit
+yourself after that.

 #### Running the Tests
 
 It's a good idea to write tests to exercise any new features,
