Github api with PHP - api

Question

Im new in php and im trying to make a script who will create a new repository in github and catch a document that i have in my pc and make a commit in this new repository. This script will be executed in cmd. I search for github api and I have downloaded any folders with several files, i installed some things with a composer, but i cant create a new instance of github in my php.
I don't know anything about this, I spend two days in this and i cant write a function to talk with github. In the site of github developer I dont understand anything, I really need to do this, and im very lost. Im using PhpStorm 6.0.3.
What i cant understand:
1- The api is a folder with a lot of files? Or is a library who is imported in the phpstorm? How i put this in the phpstorm for i can get the methods and create my functions?
2- Where i get the methods for talk with the github api? Where i can see them? In github developer i dont understand nothing.
I see a question similar, but dont help me much.
Please help me
EDIT
I downloaded an api, and i use the composer require, apparently everything is fine, but when i execute some file to test the api, the same error pops up. The program cant find some files that is in the project, in the same folder.
Ex: PHP Fatal error: Interface 'Github\Api\ApiInterface' not found in D:\php-github-api-master\lib\Github\Api\AbstractApi.php on line 15
In anothers files the same error appears, i put "use" referecing the files that im trying to use, but dont work. Ex: use Github\Api\ApiInterface;
EDIT
This code will create a new repository right? When i execute this code I get the error above, Class 'Github\Api\AbstractApi' not found, but the class is in there.
class Repo extends AbstractApi
{
public function create(
$name,
$description = '',
$homepage = '',
$public = true,
$organization = null,
$hasIssues = false,
$hasWiki = false,
$hasDownloads = false,
$teamId = null,
$autoInit = false
) {
$path = null !== $organization ? 'orgs/'.$organization.'/repos' : 'user/repos';
$parameters = array(
'name' => $name,
'description' => $description,
'homepage' => $homepage,
'private' => !$public,
'has_issues' => $hasIssues,
'has_wiki' => $hasWiki,
'has_downloads' => $hasDownloads,
'auto_init' => $autoInit
);
if ($organization && $teamId) {
$parameters['team_id'] = $teamId;
}
return $this->post($path, $parameters);
}
}
Thanks,
Johann.

I finish my script, everything was done correct, sorry for my obviosly questions and thanks for who was answer me. My code:
<?php
include "vendor/autoload.php";
$client = new \Github\Client();
$username = "JohannLucas";
$password = "mypassword";
$method = Github\Client::AUTH_HTTP_PASSWORD;
//authenticate
$client->authenticate($username, $password, $method);
//Apagar Repositório
//$client->api('repo')->remove('JohannLucas', 'teste');
//Criar Repositório
$client->api('repo')->create('olamundo', 'Repositorio criado com o github api', 'http://my-repo-homepage.org', true);
//Commit
$committer = array('name' => 'JohannLucas', 'email' => 'johann.lucas#hotmail.com');
$path = "teste.txt";
$commitMessage = "Commit do teste.txt";
$content = "Olá Mundo!";
$branch = "master";
$repo = "olamundo";
$fileInfo = $client->api('repo')->contents()->create('JohannLucas', 'olamundo', $path, $content, $commitMessage, $branch, $committer);
print_r("Foi!");
Thanks!
Johann
