+
+## Examples
+
+**In**
+
+```javascript
+var re = /(?<year>\d{4})-(?<month>\d{2})|(?<month>\d{2})-(?<year>\d{4})/;
+
+console.log(re.exec("02-1999").groups.year);
+```
+
+**Out**
+
+```javascript
+var re = _wrapRegExp(/(\d{4})-(\d{2})|(\d{2})-(\d{4})/, {
+  year: [1, 4],
+  month: [2, 3],
+});
+
+console.log(re.exec("02-1999").groups.year);
+```
+
+## Installation
+
+```sh
+npm install --save-dev @babel/plugin-proposal-duplicated-named-capturing-groups-regex
+```
+
+## Usage
+
+### With a configuration file (Recommended)
+
+```json
+{
+  "plugins": ["@babel/plugin-proposal-duplicated-named-capturing-groups-regex"]
+}
+```
+
+### Via CLI
+
+```sh
+babel --plugins @babel/plugin-proposal-duplicated-named-capturing-groups-regex script.js
+```
+
+### Via Node API
+
+```javascript
+require("@babel/core").transformSync("code", {
+  plugins: ["@babel/plugin-proposal-duplicated-named-capturing-groups-regex"],
+});
+```
+
+## Options
+
+### `runtime`
+
+`boolean`, defaults to `true`
+
+When this option is disabled, Babel doesn't wrap RegExps with the `_wrapRegExp` helper.
+The output only supports internal group references, and not runtime properties:
+
+```js
+var stringRe = /(?:(?<quote>")|(?<quote>')).*?\k<quote>/;
+
+stringRe.test("'foo'"); // "true", works
+stringRe.exec("'foo'").groups.quote; // undefined
+```
