Before starting a project it helps to understand the file structure.

\api
\app
    \controllers
    \scripts
    \views
    \app.js
\assets
    \css
    \images
\lib
    \components
    \themes
    \vendors
    common.js
    engine.css
    engine.js
    handlebars.min.js
    include.js
    jsonpath.min.js
    md5.js
    moment.min.js
    swipe.js
    ui.js
index.html
index.js

With the base package in place you are ready to start building your app (see building an app).

To install EngineJS simple download the latest release and unzip to your application root folder.

If you don't already have a web server installed I suggest you pop over to https://www.apachefriends.org and get yourself XAMPP.

Once XAMPP is installed, create yourself a sub folder for the app under htdocs and unzip EngineJS into that folder. Then use your browser view it by simply typing in http://localhost/myapp/
