I have problem with including my files into a plugin, mycontactform folder and files within it works fine in localhost and I can do CROD methods but, I don't know how to share my files into plugin.

<?php
/*
*Plugin Name: Contact Form
*Plugin URl" 
*Description: A plugin for contact form and application form
*Version:1.0
*Author: Jetmir Zela
*Author URl: 
*License:GPL2

*/
add_action('contact', 'contactform_example_function');

function contactform_example_function(){
include('home.php');
}

add_shortcode('contact', 'contactform_example_function');
?>
