Contribution install and run

[juancjara]

I would be nice to have documentation about running the project, I know this is a static project for now, but it will probably grow and maybe you would use webpack or more libraries (live reloading, etc). With this PR you would only need to install the dependencies npm install and npm start to start the app, then it would be exposed on localhost:8080

@juancjara Nice idea !

Many of webpack beginners will learn how to configure it. 🙂

I wonder if you guys can start a discussion on using webpack vs. Gulp. Pros/Cons...

We have a pull request open for integrating gulp, but I'm interested in hearing more about webpack.

I think that is more about personal preferences, I used to use grunt/gulp but then I switch to webpack, things looks easier to configure and currently you have smart defaults on version 4. Also webpack looks like more configuration than writing code like gulp does.IMO I will go with Webpack because it's the common default on proyects, I saw that on many repos.
