Josh Adell's Blog: PHP Fog Quickstart
Being it was Christmas and all, I decided to give myself a present and sign up. I was very surprised by how easy it was to get up and running. I managed to build a simple "echo" service in about i.8 minutes, following roughly these steps.
It was as simple as "launching" a new custom application, waiting for it to become available, cloning the git repository and setting up a simple app. In his case, it's a basic Silex-based app that makes a simple site to greet users with a "Hello world" message. Throw in a basic .htaccess file and the app is all set to push.
