title: Laravel - Facade explanation and code example
body: <p>whenever we call a Facade Method it involves Facade design pattern and it called for some hidden class by using Facade. for instance for File, if we call </p>
  
  <pre><code>File::get(public_path().'test.txt');
  </code></pre>
  
  <p>this will call the method in class</p>
  
  <pre><code>Illuminate\Filesystem\Filesystem
  </code></pre>
  
  <p>and in this class we will have get($path) method. </p>
  
  <p>Now my question is how Facade Abstract Class is related to File and Filesystem and where Laravel is telling them to call get in Filesystem. is there some kind of register which i am missing ?? i want to find complete link. </p>
