title: Unable to install my own created laravel package
body: <p>Few days ago I created a laravel package using guide provided in this <a href="http://kaltencoder.com/2015/07/laravel-5-package-creation-tutorial-part-1/" rel="nofollow">link</a> and submitted it to packagist.org website. They provided me a composer code to install it. You can find the package <a href="https://packagist.org/packages/mansa/simplepay" rel="nofollow">here</a>. When I tried to install it using composer and it is giving me following error. </p>
  
  <pre><code>[InvalidArgumentException]
  Could not find package mansa/simplepay at any version for your 
  minimum-stability (stable). Check the package spelling or your minimum-stability
  </code></pre>
  
  <p>Can you please tell me how can I install this package?</p>
  
  <p>I am using Ubuntu with PHP 7.0 and laravel 5.3.6. 
  I am not much familiar with laravel.</p>
