+# QRCode Terminal Edition [![Build Status][travis-ci-img]][travis-ci-url]
+
+> Going where no QRCode has gone before.
+
+![Basic Example][basic-example-img]
+
+# Node Library
+
+## Install
+
+Can be installed with:
+
+    $ npm install qrcode-terminal
+
+and used:
+
+    var qrcode = require('qrcode-terminal');
+
+## Usage
+
+To display some data to the terminal just call:
+
+    qrcode.generate('This will be a QRCode, eh!');
+
+You can even specify the error level (default is 'L'):
+    
+    qrcode.setErrorLevel('Q');
+    qrcode.generate('This will be a QRCode with error level Q!');
+
+If you don't want to display to the terminal but just want to string you can provide a callback:
+
+    qrcode.generate('http://github.com', function (qrcode) {
+        console.log(qrcode);
+    });
+
+If you want to display small output, provide `opts` with `small`:
+
+    qrcode.generate('This will be a small QRCode, eh!', {small: true});
+
+    qrcode.generate('This will be a small QRCode, eh!', {small: true}, function (qrcode) {
+        console.log(qrcode)
+    });
+
+# Command-Line
+
+## Install
+
+    $ npm install -g qrcode-terminal
+
+## Usage
+
+    $ qrcode-terminal --help
+    $ qrcode-terminal 'http://github.com'
+    $ echo 'http://github.com' | qrcode-terminal
+
+# Support
+
+- OS X
+- Linux
+- Windows
+
+# Server-side
+
+[node-qrcode][node-qrcode-url] is a popular server-side QRCode generator that
+renders to a `canvas` object.
+
+# Developing
+
+To setup the development envrionment run `npm install`
+
+To run tests run `npm test`
