<p>I always put the code at the end of my posts. Since I always have doubts about how many people are interested in what I do, today will be different. I will share the code with those who ask it to me in any of the following ways:</p>
<ul>
<li>Sending me a direct message on <a target="_blank" rel="nofollow" href="https://twitter.com/aschinchon">Twitter</a></li>
<li>Droping me an <a target="_blank" rel="nofollow" href="https://fronkonstin.com/about/">email</a></li>
</ul>
<p>Cheers!</p>
