title: Best way to customize Spree?
body: <p>I need to modify Spree (functionality and views). But Spree installs as a gem (it's not simple application), I believe it's actually a Rails engine right? I'm pretty new at all of this.</p>
  
  <p>But what is exactly the best way to grab Spree and customize it entirely to create your own ecommerce solution?</p>
  
  <p>Thank you.</p>
  
  <p>PS: Using Ruby 1.8.7 and Rails 3.</p>
