+## 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)
+[![devDependency Status](https://david-dm.org/estools/escodegen/dev-status.svg)](https://david-dm.org/estools/escodegen#info=devDependencies)
+
+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`.

+- Experimental support for [JSX](https://facebook.github.io/jsx/), a syntax extension for [React](https://facebook.github.io/react/)
+- Optional tracking of syntax node location (index-based and line-column)
+- [Heavily tested](http://esprima.org/test/ci.html) (~1300 [unit tests](https://github.com/jquery/esprima/tree/master/test/fixtures) with [full code coverage](https://codecov.io/github/jquery/esprima))
+
+### API
+
+Esprima can be used to perform [lexical analysis](https://en.wikipedia.org/wiki/Lexical_analysis) (tokenization) or [syntactic analysis](https://en.wikipedia.org/wiki/Parsing) (parsing) of a JavaScript program.
+
+A simple example on Node.js REPL:
+
+```javascript
+> var esprima = require('esprima');
+> var program = 'const answer = 42';
+
+> esprima.tokenize(program);
+[ { type: 'Keyword', value: 'const' },
+  { type: 'Identifier', value: 'answer' },
+  { type: 'Punctuator', value: '=' },
+  { type: 'Numeric', value: '42' } ]
+  
+> esprima.parse(program);
+{ type: 'Program',
+  body:
+   [ { type: 'VariableDeclaration',
+       declarations: [Object],
+       kind: 'const' } ],
+  sourceType: 'script' }
+```
