title: what does it mean in blade @extends('some::thing')
body: <p>Today I have installed <code>jeroennoten/laravel-adminlte</code> and after following all the installation command I created a view and just wrote the line </p>
  
  <pre><code>@extends('adminlte::page')
  </code></pre>
  
  <p>and it works fine but I do not understand how it works? specially this <code>::</code> symbol? I checked the laravel documentation but could not find anything.</p>
  
  <p>Please help me by explaining it or give some article/tutorial link from where I can learn more.</p>
