+Parse CSV with JavaScript
+========================================
+
+Papa Parse is the fastest in-browser CSV (or delimited text) parser for JavaScript. It is reliable and correct according to [RFC 4180](https://tools.ietf.org/html/rfc4180), and it comes with these features:
+
+- Easy to use
+- Parse CSV files directly (local or over the network)
+- Fast mode
+- Stream large files (even via HTTP)
+- Reverse parsing (converts JSON to CSV)
+- Auto-detect delimiter
+- Worker threads to keep your web page reactive
+- Header row support
+- Pause, resume, abort
+- Can convert numbers and booleans to their types
+- Optional jQuery integration to get files from `<input type="file">` elements
+- One of the only parsers that correctly handles line-breaks and quotations
+
+Papa Parse has **no dependencies** - not even jQuery.
+
+Install
+-------
+
+papaparse is available on [npm](https://www.npmjs.com/package/papaparse). It
+can be installed with the following command:
+
+    npm install papaparse
+
+If you don't want to use npm, [papaparse.min.js](https://unpkg.com/papaparse@latest/papaparse.min.js) can be downloaded to your project source.
+
+
+Homepage & Demo
+----------------
+
+- [Homepage](http://papaparse.com)
+- [Demo](http://papaparse.com/demo)
+
+To learn how to use Papa Parse:
+
+- [Documentation](http://papaparse.com/docs)
+
+The website is hosted on [Github Pages](https://pages.github.com/). Its content is also included in the docs folder of this repository. If you want to contribute on it just clone the master of this repository and open a pull request.
+
+
+Papa Parse for Node
+--------------------
+
+Papa Parse can parse a [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) instead of a [File](https://www.w3.org/TR/FileAPI/) when used in Node.js environments (in addition to plain strings). In this mode, `encoding` must, if specified, be a Node-supported character encoding. The `Papa.LocalChunkSize`, `Papa.RemoteChunkSize` , `download`, `withCredentials` and `worker` config options are unavailable.
+
+Papa Parse can also parse in a node streaming style which makes `.pipe` available.  Simply pipe the [Readable Stream](https://nodejs.org/api/stream.html#stream_readable_streams) to the stream returned from `Papa.parse(Papa.NODE_STREAM_INPUT, options)`.  The `Papa.LocalChunkSize`, `Papa.RemoteChunkSize` , `download`, `withCredentials`, `worker`, `step`, and `complete` config options are unavailable.  To register a callback with the stream to process data, use the `data` event like so: `stream.on('data', callback)` and to signal the end of stream, use the 'end' event like so: `stream.on('end', callback)`.
+
+Get Started
+-----------
+
+For usage instructions, see the [homepage](http://papaparse.com) and, for more detail, the [documentation](http://papaparse.com/docs).
+
+Tests
+-----
+
+Papa Parse is under test. Download this repository, run `npm install`, then `npm test` to run the tests.
+
+Contributing
+------------
+
+To discuss a new feature or ask a question, open an issue. To fix a bug, submit a pull request to be credited with the [contributors](https://github.com/mholt/PapaParse/graphs/contributors)! Remember, a pull request, *with test*, is best. You may also discuss on Twitter with [#PapaParse](https://twitter.com/search?q=%23PapaParse&src=typd&f=realtime) or directly to me, [@mholt6](https://twitter.com/mholt6).
+
+If you contribute a patch, ensure the tests suite is running correctly. We run continuous integration on each pull request and will not accept a patch that breaks the tests.
