  I want to contribute to phpmyadmin. I cloned the github repo in my machine using Github Desktop software. I copied the downloaded files in xampp so that I can run phpmyadmin. But when I launch the phpmyadmin page, this error occurs:  </p>
  
  <blockquote>
    <p>File ./vendor/autoload.php missing or not readable.<br>
    Most likely you did not run Composer to install library files.</p>
  </blockquote>
  
  <p>Where can I get that file? I saw something that uses composer create-project command but I don't get that where should I type that command?<br>
  I also downloaded phpmyadmin from their website and copy pasted in xampp directory and it worked well. It didn't give any such error.<br>
  What should I do?</p>
