+# babel-plugin-syntax-hermes-parser
+
+Hermes parser plugin for [Babel](https://babeljs.io/). This plugin switches Babel to use `hermes-parser` instead of the `@babel/parser`. Since Hermes parser uses C++ compiled to WASM it is significantly faster and provides full syntax support for Flow.
+
+## Install
+
+Using npm:
+
+```sh
+npm install --save-dev babel-plugin-syntax-hermes-parser
+```
+
+or using yarn:
+
+```sh
+yarn add babel-plugin-syntax-hermes-parser --dev
+```
+
+# Usage
+
+The plugin can be enabled via:
+
+```
+// babel.config.json
+{
+  "plugins": ["babel-plugin-syntax-hermes-parser"]
+}
+```
+
+If parser options need to be provide you can do so via the `parserOpts` config:
+
+```
+// babel.config.json
+{
+  "plugins": ["babel-plugin-syntax-hermes-parser"],
+  "parserOpts": {
+    "allowReturnOutsideFunction": true
+  }
+}
+```
