As we're currently moving everything to github and working on enabling composer for installation we have come up with a new basic installation process. Of course we try to simplify it further.

SilverCart: Basic installation from scratch with composer

1. composer create-project silverstripe/installer silvercart_demo
2. cd silvercart_demo
3. composer require silvercart/silvercart
4. change the class definitions in mysite/code/Page.php to:
   class Page extends SilvercartPage
   class Page_Controller extends SilvercartPage_Controller
5. open website in your browser and finish SilverStripe installation process with:
   Theme selection: empty theme (this is the only necessary setting for SilverCart)
6. Open CMS backend
7. Settings-> Email Settings: enter valid Email sender
8 Settings-> Add Example data
   Add Example Data (this might take a few minutes!)
   Add Example Configuration
