+## black-primer
+
+`black-primer` is used by CI to pull down well-known _Black_ formatted projects and see
+if we get source code changes. It will error on formatting changes or errors. Please run
+before pushing your PR to see if you get the actions you would expect from _Black_ with
+your PR. You may need to change
+[primer.json](https://github.com/psf/black/blob/master/src/black_primer/primer.json)
+configuration for it to pass.
+
+For more `black-primer` information visit the
+[documentation](https://github.com/psf/black/blob/master/docs/black_primer.md).
