+
+_quoted-printable_ is a character encoding–agnostic JavaScript implementation of [the `Quoted-Printable` content transfer encoding as defined by RFC 2045](https://tools.ietf.org/html/rfc2045#section-6.7). It can be used to encode plaintext to its `Quoted-Printable` encoding, or the other way around (i.e. decoding). [Here’s an online demo using the UTF-8 character encoding.](https://mothereff.in/quoted-printable)
+
+## Installation
+
+Via [npm](https://www.npmjs.com/):
+
+```bash
+npm install quoted-printable
+```
+
+Via [Bower](http://bower.io/):
+
+```bash
+bower install quoted-printable
+```
+
+Via [Component](https://github.com/component/component):
+
+```bash
+component install mathiasbynens/quoted-printable
+```
+
+In a browser:
+
+```html
+<script src="quoted-printable.js"></script>
+```
+
+In [Node.js](https://nodejs.org/), [io.js](https://iojs.org/), [Narwhal](http://narwhaljs.org/), and [RingoJS](http://ringojs.org/):
+
+```js
+var quotedPrintable = require('quoted-printable');
+```
+
+In [Rhino](http://www.mozilla.org/rhino/):
+
+```js
+load('quoted-printable.js');
+```
+
+Using an AMD loader like [RequireJS](http://requirejs.org/):
+
+```js
+require(
+  {
+    'paths': {
+      'quoted-printable': 'path/to/quoted-printable'
+    }
+  },
+  ['quoted-printable'],
+  function(quotedPrintable) {
+    console.log(quotedPrintable);
+  }
+);
+```
+
+## API
+
+### `quotedPrintable.version`
+
+A string representing the semantic version number.
+
+### `quotedPrintable.encode(input)`
+
+This function takes an encoded byte string (the `input` parameter) and `Quoted-Printable`-encodes it. Each item in the input string represents an octet as per the desired character encoding. Here’s an example that uses UTF-8:
+
+```js
+var utf8 = require('utf8');
+
+quotedPrintable.encode(utf8.encode('foo=bar'));
+// → 'foo=3Dbar'
+
+quotedPrintable.encode(utf8.encode('Iñtërnâtiônàlizætiøn☃💩'));
+// → 'I=C3=B1t=C3=ABrn=C3=A2ti=C3=B4n=C3=A0liz=C3=A6ti=C3=B8n=E2=98=83=F0=9F=92=\r\n=A9'
+```
+
+### `quotedPrintable.decode(text)`
+
+This function takes a string of text (the `text` parameter) and `Quoted-Printable`-decodes it. The return value is a ‘byte string’, i.e. a string of which each item represents an octet as per the character encoding that’s being used. Here’s an example that uses UTF-8:
+
+```js
+var utf8 = require('utf8');
+
+utf8.decode(quotedPrintable.decode('foo=3Dbar'));
+// → 'foo=bar'
+
+utf8.decode(quotedPrintable.decode('I=C3=B1t=C3=ABrn=C3=A2ti=C3=B4n=C3=A0liz=C3=A6ti=C3=B8n=E2=98=83=F0=9F=92=\r\n=A9'));
+// → 'Iñtërnâtiônàlizætiøn☃💩'
+```
+
+### Using the `quoted-printable` binary
+
+To use the `quoted-printable` binary in your shell, simply install _quoted-printable_ globally using npm:
+
+```bash
+npm install -g quoted-printable
+```
+
+After that, you’ll be able to use `quoted-printable` on the command line. Note that while the _quoted-printable_ library itself is character encoding–agnostic, the command-line tool applies the UTF-8 character encoding on all input.
+
+```bash
+$ quoted-printable --encode 'foo=bar'
+foo=3Dbar
+
+$ quoted-printable --decode 'foo=3Dbar'
+foo=bar
+```
+
+Read a local text file, `Quoted-Printable`-encode it, and save the result to a new file:
+
+```bash
+$ quoted-printable --encode < foo.txt > foo-quoted-printable.txt
+```
+
+Or do the same with an online text file:
+
+```bash
+$ curl -sL 'https://mths.be/brh' | quoted-printable --encode > quoted-printable.txt
+```
+
+Or, the opposite — read a local file containing a `Quoted-Printable`-encoded message, decode it back to plain text, and save the result to a new file:
+
+```bash
+$ quoted-printable --decode < quoted-printable.txt > original.txt
+```
+
+See `quoted-printable --help` for the full list of options.
+
+## Support
+
+_quoted-printable_ is designed to work in at least Node.js v0.10.0, io.js v1.0.0, Narwhal 0.3.2, RingoJS 0.8-0.11, PhantomJS 1.9.0, Rhino 1.7RC4, as well as old and modern versions of Chrome, Firefox, Safari, Opera, and Internet Explorer.
+
+## Unit tests & code coverage
+
+After cloning this repository, run `npm install` to install the dependencies needed for development and testing. You may want to install Istanbul _globally_ using `npm install istanbul -g`.
+
+Once that’s done, you can run the unit tests in Node using `npm test` or `node tests/tests.js`. To run the tests in Rhino, Ringo, Narwhal, and web browsers as well, use `grunt test`.
+
+To generate the code coverage report, use `grunt cover`.
