+# stylehacks
+
+> Detect/remove browser hacks from CSS files.
+
+
+## Install
+
+With [npm](https://npmjs.org/package/stylehacks) do:
+
+```
+npm install stylehacks --save
+```
+
+
+## Example
+
+In its default mode, stylehacks will remove hacks from your CSS file, based on
+the browsers that you wish to support.
+
+### Input
+
+```css
+h1 {
+    _color: white;
+    color: rgba(255, 255, 255, 0.5);
+}
+```
+
+### Output
+
+```css
+h1 {
+    color: rgba(255, 255, 255, 0.5);
+}
+```
+
+
+## API
+
+### `stylehacks.detect(node)`
+
+Type: `function`  
+Returns: `boolean`
+
+This method will take any PostCSS *node*, run applicable plugins depending on
+its type, then will return a boolean depending on whether it found any of
+the supported hacks. For example, if the `decl` node found below is passed to
+the `detect` function, it will return `true`. But if the `rule` node is passed,
+it will return `false` instead.
+
+```css
+h1 { _color: red }
+```
+
+### `postcss([ stylehacks(opts) ])`
+
+stylehacks can also be consumed as a PostCSS plugin. See the
+[documentation](https://github.com/postcss/postcss#usage) for examples for
+your environment.
+
+#### options
+
+##### lint
+
+Type: `boolean`  
+Default: `false`
+
+If lint mode is enabled, stylehacks will not remove hacks from the CSS; instead,
+it will add warnings to `Result#messages`.
+
+
+## Related
+
+stylehacks works well with your existing PostCSS setup:
+
+* [stylelint] - Comprehensive & modern CSS linter, to ensure that your code
+  style rules are respected.
+
+
+## Contributing
+
+Pull requests are welcome. If you add functionality, then please add unit tests
+to cover it.
