+## Escodegen
+[![npm version](https://badge.fury.io/js/escodegen.svg)](http://badge.fury.io/js/escodegen)
+[![Build Status](https://secure.travis-ci.org/estools/escodegen.svg)](http://travis-ci.org/estools/escodegen)
+[![Dependency Status](https://david-dm.org/estools/escodegen.svg)](https://david-dm.org/estools/escodegen)

+
+Escodegen ([escodegen](http://github.com/estools/escodegen)) is an
+[ECMAScript](http://www.ecma-international.org/publications/standards/Ecma-262.htm)
+(also popularly known as [JavaScript](http://en.wikipedia.org/wiki/JavaScript))
+code generator from [Mozilla's Parser API](https://developer.mozilla.org/en/SpiderMonkey/Parser_API)
+AST. See the [online generator](https://estools.github.io/escodegen/demo/index.html)
+for a demo.
+
+
+### Install
+
+Escodegen can be used in a web browser:
+
+    <script src="escodegen.browser.js"></script>
+
+escodegen.browser.js can be found in tagged revisions on GitHub.
+
+Or in a Node.js application via npm:
+
+    npm install escodegen
+
+### Usage
+
+A simple example: the program
+
+    escodegen.generate({
+        type: 'BinaryExpression',
+        operator: '+',
+        left: { type: 'Literal', value: 40 },
+        right: { type: 'Literal', value: 2 }
+    });
+
+produces the string `'40 + 2'`.
+
+See the [API page](https://github.com/estools/escodegen/wiki/API) for
+options. To run the tests, execute `npm test` in the root directory.
+
+### Building browser bundle / minified browser bundle
+
+At first, execute `npm install` to install the all dev dependencies.
+After that,
+
+    npm run-script build
+
+will generate `escodegen.browser.js`, which can be used in browser environments.
+
+And,
+
+    npm run-script build-min
+
+will generate the minified file `escodegen.browser.min.js`.
