title: Change Root in ActiveAdmin
body: <p>right now my active_admin gem in Rails has a default url of </p>
  
  <p>www.home.com/admin</p>
  
  <p>however the active admin resides in </p>
  
  <p>www.home.com/group/admin</p>
  
  <p>How can I make it so that every link in active admin will route to /group/admin/[next link]</p>
  
  <p>I tried Gmat's solution below and this is what happened:</p>

  <p>I apologize for the formatting. The point is that all the links www.home.com/group/[anything] is broken. </p>
