Atelier Download

To check if you already have Java installed, and if so what version enter this in an OS Terminal: java –version
To install Java for the first time, a newer version of Java, or a different bitness of Java (Java bitness should match the Eclipse bitness) check the Oracle website: http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

Download the installer from the Eclipse website: https://eclipse.org/downloads/
Start the Eclipse Installer and select the package you want to install. We suggest you get Eclipse IDE for JavaScript and Web Developers which includes essential tools for JavaScript, HTML, CSS and XML languages support. You can always add or remove plugins later.
