title: Where is Illuminate?
body: <p>Every time when I try to do some modifications in certain area, <em>Authentication for example</em>, I end up finding everything is declared in <code>Illuminate\Foundation\...</code>.</p>
  
  <p>Okay, now all I need to do is get to that location and look into some codes.</p>
  
  <p>But hey, where is this <code>Illuminate</code> and all stuff???</p>
  
  <p>I don't see any folders named Illuminate anywhere in my Laravel package.</p>
  
  <p>Tried to search for the solution but I guess I'm the only silly person who lacks ability in understanding some basics.</p>
