+# eslint-formatter-codeframe
+
+> ESLint’s official `codeframe` formatter, extracted from ESLint 7
+
+This formatter has been removed from ESLint 8 so it lives as a standalone module here.
+
+**Warning:** This module is not maintained. If you're an ESLint contributor or dependable open-sourcerer, open an issue here and I'll pass you this repo and npm name. You can also ping me on Twitter [@fregante](https://twitter.com/fregante)
+
+## Install
+
+```sh
+npm install --save-dev eslint-formatter-codeframe
+```
+
+## Usage
+
+More information about formatters can be found on https://eslint.org/docs/user-guide/formatters/
+
+```
+eslint --format codeframe
+```
+
+## Example output
+
+```
