+# @babel/plugin-transform-unicode-property-regex
+
+Compile [Unicode property escapes](https://github.com/mathiasbynens/regexpu-core/blob/master/property-escapes.md) (`\p{…}` and `\P{…}`) in Unicode regular expressions to ES5 or ES6 that works in today’s environments.
+
+**Note:** the Unicode property escape syntax is non-standard and may or may not reflect what eventually gets specified.
+
+[Here’s an online demo.](https://mothereff.in/regexpu#input=var+regex+%3D+/%5Cp%7BScript_Extensions%3DGreek%7D/u%3B&unicodePropertyEscape=1)
+
+## Installation
+
+```sh
+$ npm install @babel/plugin-transform-unicode-property-regex
+```
+
+## Usage
+
+### Via `.babelrc` (recommended)
+
+`.babelrc`
+
+```json
+{
+  "plugins": ["transform-unicode-property-regex"]
+}
+```
+
+### Via CLI
+
+```sh
+$ babel --plugins transform-unicode-property-regex script.js
+```
+
+### Via Node.js API
+
+```js
+require('@babel/core').transform(code, {
+  'plugins': ['transform-unicode-property-regex']
+});
+```
+
+To transpile to ES6/ES2015:
+
+```js
+require('@babel/core').transform(code, {
+  'plugins': [
+    ['transform-unicode-property-regex', { 'useUnicodeFlag': true }]
+  ]
+});
+```
