 `flake8-annotations` is a plugin for [Flake8](http://flake8.pycqa.org/en/latest/) that detects the absence of [PEP 3107-style](https://www.python.org/dev/peps/pep-3107/) function annotations.

 ### `--respect-type-ignore`
-Suppress linting errors for functions annotated with a `# type: ignore` comment.
+Suppress linting errors for functions annotated with a `# type: ignore` comment. Support is also provided for module-level blanket ignores (see: [mypy: Ignoring a whole file](https://mypy.readthedocs.io/en/stable/common_issues.html#ignoring-a-whole-file)). 
 
 **NOTE:** Type ignore tags are not considered, e.g. `# type: ignore[arg-type]` is treated the same as `# type: ignore`.
+**NOTE:** Module-level suppression is only considered for the `# mypy: ignore-errors` or `# type: ignore` tags when provided as the sole contents of the first line of the module.
