The Oro Platform offers developers the exact business application platform they’ve been looking for, by combining the tools they need. Built in PHP5 and the Symfony2 framework, it seamlessly integrates into OroCRM or works entirely standalone. Developing custom business applications has never been so easy.
Platform is a package that requires an application to run it. A platform-application is an example of such application which simplifies initial project setup and configuration.
In order to define dependency on platform in your project just add this to composer.json file:
"require": {
"oro/platform": "1.0.*"
}
