+
+[PostCSS Focus Visible] lets you use the `:focus-visible` pseudo-class in
+CSS, following the [Selectors Level 4 specification].
+
+It is the companion to the [focus-visible polyfill].
+
+[!['Can I use' table](https://caniuse.bitsofco.de/image/css-focus-visible.png)](https://caniuse.com/#feat=css-focus-visible)
+
+```css
+:focus:not(:focus-visible) {
+  outline: none;
+}
+
+/* becomes */
+
+:focus:not(.focus-visible) {
+  outline: none;
+}
+
+:focus:not(:focus-visible) {
+  outline: none;
+}
+```
+
+[PostCSS Focus Visible] duplicates rules using the `:focus-visible` pseudo-class
+with a `.focus-visible` class selector, the same selector used by the
+[focus-visible polyfill]. This replacement selector can be changed using the
+`replaceWith` option. Also, the preservation of the original `:focus-visible`
+rule can be disabled using the `preserve` option.
+
+## Usage
+
+Add [PostCSS Focus Visible] to your project:
+
+```bash
+npm install postcss-focus-visible --save-dev
+```
+
+Use [PostCSS Focus Visible] to process your CSS:
+
+```js
+const postcssFocusVisible = require('postcss-focus-visible');
+
+postcssFocusVisible.process(YOUR_CSS /*, processOptions, pluginOptions */);
+```
+
+Or use it as a [PostCSS] plugin:
+
+```js
+const postcss = require('postcss');
+const postcssFocusVisible = require('postcss-focus-visible');
+
+postcss([
+  postcssFocusVisible(/* pluginOptions */)
+]).process(YOUR_CSS /*, processOptions */);
+```
+
+[PostCSS Focus Visible] runs in all Node environments, with special
+instructions for:
+
+| [Node](INSTALL.md#node) | [PostCSS CLI](INSTALL.md#postcss-cli) | [Webpack](INSTALL.md#webpack) | [Create React App](INSTALL.md#create-react-app) | [Gulp](INSTALL.md#gulp) | [Grunt](INSTALL.md#grunt) |
+| --- | --- | --- | --- | --- | --- |
+
+## Options
+
+### preserve
+
+The `preserve` option defines whether the original selector should remain. By
+default, the original selector is preserved.
+
+```js
+focusVisible({ preserve: false });
+```
+
+```css
+:focus:not(:focus-visible) {
+  outline: none;
+}
+
+/* becomes */
+
+:focus:not(.focus-visible) {
+  outline: none;
+}
+```
+
+### replaceWith
+
+The `replaceWith` option defines the selector to replace `:focus-visible`. By
+default, the replacement selector is `.focus-visible`.
+
+```js
+focusVisible({ replaceWith: '[focus-visible]' });
+```
+
+```css
+:focus:not(:focus-visible) {
+  outline: none;
+}
+
+/* becomes */
+
+:focus:not([focus-visible]) {
+  outline: none;
+}
+
+:focus:not(:focus-visible) {
+  outline: none;
+}
+```
