+
+ES6UMD is a template for writing micro ES6 Javascript libraries that run both on Node.js and the browser.
+
+ES6UMD uses [Babel](https://babeljs.io) to compile ES6 Javascript code to ES5. It uses [Browserify](http://browserify.org) to bundle all the Javascript files in one Javascript UMD file that can run both on Node.js and the browser.
+
+ES6UMD uses [Gulp](http://gulpjs.com) for the build.
+
+ES6UMD relies on [Mocha](https://mochajs.org) and [Chai](http://chaijs.com) for unitary testing. It relies on [Istanbul](https://gotwarlost.github.io/istanbul/) for code coverage.
+
+ES6UMD uses [Travis CI](https://travis-ci.org) for continuous integration and [Coveralls.io](https://coveralls.io) to display test coverage.
+
+
+## Quick Startup
+
+You can easily get your first ES6UMD library running in a couple of minutes by just typing a few command lines. But first, you need to create an empty folder. It will contain your library.
+
+Then, you have to install the `es6umd` package globally. Open a terminal session and type the command line:
+
+```
+npm install es6umd -g
+```
+
+Or, if you don't have the rights to install ES6UMD globally, you can install it locally in your project. Open a terminal session, move to your working directory - the empty folder you created - and type the following command line:
+
+```
+npm install es6umd
+```
+
+Now populate your empty folder and create your first UMD library with these command lines:
+
+```
+// populate (// means a comment and not a command line!)
+es6umd populate -n myapp
+// Or, if you installed the package locally:
+./node_modules/es6umd/bin/es6umd.js populate -n <name of your library>
+// Install Node.js packages
+npm install
+```
+
+Now your project folder contains the following files:
+
+```
+Your project Folder
+      |_ docs                 // The Gitbook documentation of your project,
+      |_ lib
+      |   |_ lib.js           // Your lib converted by babel and browserify to an ES5 module,
+      |_ src
+      |  |_ main.js           // Your ES6 main library,
+      |  |_ lib.js            // A second ES6 library,
+      |_ tasks
+      |   |_ ...              // The Gulp tasks to build your project,
+      |_  test
+      |     |_ main.js        // Your Mocha, Chai test file,
+      |_ .babelrc             // The configuration file for Babel,
+      |_ .eslintrc            // A Configuration file for the ESLint linter tool (if you use it),
+      |_ .gitignore           // Files that Git must ignore (if you use git),
+      |_ .travis.yml          // A configuration file for Travis CI (if you use it),
+      |_ .CHANGELOG.md        // The changes between your different versions,
+      |_ .gulpfile.js         // The main Gulp task,
+      |_ index.js             // The link to your ES6 libraries,
+      |_ LICENSE.md           // The license that applies to your library (here MIT),
+      |_ package-lock.json    // The NPM dependency tree,
+      |_ package.json         // The NPM package file,
+      |_ README.md            // Your README file,
+```
+
+This project folder is now an NPM package.
+
+
+### How to build it
+
+Your `package.json` file provides two scripts to build and update your library:
+
+  * `npm run build`,
+  * `npm run watch`.
+
+`npm run build` creates a folder `_dist` that contains the Javascript file `<name of your library>.js`. This file is an UMD javascript library that bundles all the es6 files of your project (here index.js, lib/main.js and lib/lib.js).
+
+`npm run watch` updates on the fly `_dist/<name of your library>.js` each time you modify a Javascript file in your project.
+
+
+## How to test it
+
+Your `package.json` file contains three scripts to test your UMD library:
+
+  * `npm run test`,
+  * `npm run check-coverage`,
+  * `npm run display-coverage`.
+
+`npm run test` executes the tests and computes the test coverage.
+
+`npm run check-coverage` checks if the test coverage matches the requirements. Here 100%.
+
+`npm run display-coverage` opens your browser and reports the test coverage.
+
+
+## How to use it
+
+On Node.js, your project folder is viewed as a NPM package (usually, it has the same name as your library). Choose a working directory outside your project folder, create a folder `node_modules` and copy your project folder into `node_modules`. Then, on your terminal, type (at your working directory level):
+
+```
+node
+> var MyLib = require('<name of your project folder>');
+undefined
+> var mylib = new MyLib();
+undefined
+> mylib.getString();
+'I am a string!'
+> mylib.getArray();
+[ 1, 2, 3 ]
+>
+```
+
+On the browser, pick-up the Javascript file `_dist/<name of your library>.js` and add it as a script in your HTML file. `<name of your library>.js` is an immediately-invoked function expression. It attaches the `UMDLib` variable to the current context.
+
+```
+<!DOCTYPE html>
+<html>
+  <body>
+    <script src="<name of your library>.js"></script>
+    <script>
+      var lib = new <name of your library>();
+      lib.getString();
+      lib.getArray();
+    </script>
+  </body>
+</html>
+```
+
+Enjoy!
