Defining the correct path to Twilio services directory

Question

I don't have the ability to use composer to install twilio-php library so I am installing it manually. It is very confusing for me as a nubie to understand how to initiate a new service...notice the first require statement it points to a directory of Services/Twilio. After downloading the Twilio-Php library there is no directory named Services. Also the $client= new Services Twilio will need the right path as well. What do I do, Help?

<?php 
   require("Services/Twilio.php"); 
   require("database.php"); 

   // initiate phone call via Twilio REST API     
   // Set our AccountSid and AuthToken  
   $AccountSid = "ACxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; 
   $AuthToken = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"; 

   // Instantiate a new Twilio Rest Client  
   $client = new Services_Twilio($AccountSid, $AuthToken); 

Answer 1

The latest install instructions show the following:

 <?php
    // Require the bundled autoload file - the path may need to change
    // based on where you downloaded and unzipped the SDK
    require __DIR__ . '/twilio-php-master/Twilio/autoload.php';

In which directory did you unzip the library?
