+
+## History and Why MySQL2
+
+MySQL2 project is a continuation of [MySQL-Native][mysql-native]. Protocol parser code was rewritten from scratch and api changed to match popular [Node MySQL][node-mysql]. MySQL2 team is working together with [Node MySQL][node-mysql] team to factor out shared code and move it under [mysqljs][mysqljs] organization.
+
+MySQL2 is mostly API compatible with [Node MySQL][node-mysql] and supports majority of features. MySQL2 also offers these additional features:
+
+- Faster / Better Performance
+- [Prepared Statements][docs-prepared-statements]
+- MySQL Binary Log Protocol
+- [MySQL Server][docs-mysql-server]
+- Extended support for Encoding and Collation
+- [Promise Wrapper][docs-promise-wrapper]
+- Compression
+- SSL and [Authentication Switch][docs-authentication-switch]
+- [Custom Streams][docs-streams]
+- [Pooling][docs-qs-pooling]
+
+## Installation
+
+MySQL2 is free from native bindings and can be installed on Linux, Mac OS or Windows without any issues.
+
+```bash
+npm install --save mysql2
+```
+
+If you are using TypeScript, you will need to install `@types/node`.
+
+```bash
+npm install --save-dev @types/node
+```
+
+> For TypeScript documentation and examples, see [here][docs-typescript-docs].
+
+## Documentation
+
+- [Quickstart][docs-base]
+  - [First Query][docs-qs-first-query], [Using Prepared Statements][docs-qs-using-prepared-statements], [Using Connection Pools][docs-qs-pooling] and more.
+- [Documentation][docs-documentation]
+- [Examples][docs-examples]
+- [FAQ][docs-faq]
+
+## Acknowledgements
+
+- Internal protocol is written by [@sidorares][sidorares] [MySQL-Native][mysql-native].
+- Constants, SQL parameters interpolation, Pooling, `ConnectionConfig` class taken from [Node MySQL][node-mysql].
+- SSL upgrade code based on [@TooTallNate][TooTallNate] [code][starttls.js].
+- Secure connection / compressed connection api flags compatible to [MariaSQL][node-mariasql] client.
+- [Contributors][contributors].

+## iconv-lite: Pure JS character encoding conversion
+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-downloads-url]
+[![License][license-image]][license-url]
+[![NPM Install Size][npm-install-size-image]][npm-install-size-url]
+
+* No need for native code compilation. Quick to install, works on Windows, Web, and in sandboxed environments.
+* Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
+  [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
+* Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
+* Intuitive encode/decode API, including Streaming support.
+* In-browser usage via [browserify](https://github.com/substack/node-browserify) or [webpack](https://webpack.js.org/) (~180kb gzip compressed with Buffer shim included).
+* Typescript [type definition file](https://github.com/ashtuchkin/iconv-lite/blob/master/lib/index.d.ts) included.
+* React Native is supported (need to install `stream` module to enable Streaming API).
+
+## Usage
+
+### Basic API
+
+```javascript
+var iconv = require('iconv-lite');
+
+// Convert from an encoded buffer to a js string.
+str = iconv.decode(Buffer.from([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
+
+// Convert from a js string to an encoded buffer.
+buf = iconv.encode("Sample input string", 'win1251');
+
+// Check if encoding is supported
+iconv.encodingExists("us-ascii")
+```
+
+### Streaming API
+
+```javascript
+// Decode stream (from binary data stream to js strings)
+http.createServer(function(req, res) {
+    var converterStream = iconv.decodeStream('win1251');
+    req.pipe(converterStream);
+
+    converterStream.on('data', function(str) {
+        console.log(str); // Do something with decoded strings, chunk-by-chunk.
+    });
+});
+
+// Convert encoding streaming example
+fs.createReadStream('file-in-win1251.txt')
+    .pipe(iconv.decodeStream('win1251'))
+    .pipe(iconv.encodeStream('ucs2'))
+    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
+
+// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
+http.createServer(function(req, res) {
+    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
+        assert(typeof body == 'string');
+        console.log(body); // full request body string
+    });
+});
+```
+
+## Supported encodings
+
+ *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
+ *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap, utf32, utf32-le, and utf32-be.
+ *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
+    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
+    Aliases like 'latin1', 'us-ascii' also supported.
+ *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2312, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
+
+See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
+
+Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
+
+Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
+
+## Encoding/decoding speed
+
+Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.12.0). 
+Note: your results may vary, so please always check on your hardware.
+
+    operation             iconv@2.1.4   iconv-lite@0.4.7
+    ----------------------------------------------------------
+    encode('win1251')     ~96 Mb/s      ~320 Mb/s
+    decode('win1251')     ~95 Mb/s      ~246 Mb/s
+
+## BOM handling
+
+ * Decoding: BOM is stripped by default, unless overridden by passing `stripBOM: false` in options
+   (f.ex. `iconv.decode(buf, enc, {stripBOM: false})`).
+   A callback might also be given as a `stripBOM` parameter - it'll be called if BOM character was actually found.
+ * If you want to detect UTF-8 BOM when decoding other encodings, use [node-autodetect-decoder-stream](https://github.com/danielgindi/node-autodetect-decoder-stream) module.
+ * Encoding: No BOM added, unless overridden by `addBOM: true` option.
+
+## UTF-16 Encodings
+
+This library supports UTF-16LE, UTF-16BE and UTF-16 encodings. First two are straightforward, but UTF-16 is trying to be
+smart about endianness in the following ways:
+ * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be 
+   overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`.
+ * Encoding: uses UTF-16LE and writes BOM by default. Use `addBOM: false` to override.
+
+## UTF-32 Encodings
+
+This library supports UTF-32LE, UTF-32BE and UTF-32 encodings. Like the UTF-16 encoding above, UTF-32 defaults to UTF-32LE, but uses BOM and 'spaces heuristics' to determine input endianness. 
+ * The default of UTF-32LE can be overridden with the `defaultEncoding: 'utf-32be'` option. Strips BOM unless `stripBOM: false`.
+ * Encoding: uses UTF-32LE and writes BOM by default. Use `addBOM: false` to override. (`defaultEncoding: 'utf-32be'` can also be used here to change encoding.)
+
+## Other notes
+
+When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
+Untranslatable characters are set to <20> or ?. No transliteration is currently supported.  
+Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see [#65](https://github.com/ashtuchkin/iconv-lite/issues/65), [#77](https://github.com/ashtuchkin/iconv-lite/issues/77)).  
+

+  //              Introduced in 2000, revised 2004. Some characters are in Unicode Plane 2 (0x2xxxx)
+
+  // Byte encodings are:
+  //  * Shift_JIS: Compatible with 0201, uses not defined chars in top half as lead bytes for double-byte
+  //               encoding of 0208. Lead byte ranges: 0x81-0x9F, 0xE0-0xEF; Trail byte ranges: 0x40-0x7E, 0x80-0x9E, 0x9F-0xFC.
+  //               Windows CP932 is a superset of Shift_JIS. Some companies added more chars, notably KDDI.
+  //  * EUC-JP:    Up to 3 bytes per character. Used mostly on *nixes.
+  //               0x00-0x7F       - lower part of 0201
+  //               0x8E, 0xA1-0xDF - upper part of 0201

+  //               0x8F, (0xA1-0xFE)x2 - 0212 plane (94x94).
+  //  * JIS X 208: 7-bit, direct encoding of 0208. Byte ranges: 0x21-0x7E (94 values). Uncommon.
+  //               Used as-is in ISO2022 family.
+  //  * ISO2022-JP: Stateful encoding, with escape sequences to switch between ASCII,
+  //                0201-1976 Roman, 0208-1978, 0208-1983.
+  //  * ISO2022-JP-1: Adds esc seq for 0212-1990.
+  //  * ISO2022-JP-2: Adds esc seq for GB2313-1980, KSX1001-1992, ISO8859-1, ISO8859-7.
+  //  * ISO2022-JP-3: Adds esc seq for 0201-1976 Kana set, 0213-2000 Planes 1, 2.
+  //  * ISO2022-JP-2004: Adds 0213-2004 Plane 1.
