+# Static class features support for Acorn
+
+[![NPM version](https://img.shields.io/npm/v/acorn-class-fields.svg)](https://www.npmjs.org/package/acorn-static-class-features)
+
+This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.
+
+It implements support for static class features as defined in the stage 3 proposal [Static class features](https://github.com/tc39/proposal-static-class-features). The emitted AST follows [an ESTree proposal](https://github.com/estree/estree/pull/180).
+
+## Usage
+
+This module provides a plugin that can be used to extend the Acorn `Parser` class:
+
+```javascript
+const {Parser} = require('acorn');
+const staticClassFeatures = require('acorn-static-class-features');
+Parser.extend(staticClassFeatures).parse('class X { static x = 0 }');
+```
