-Please be aware, that there are issues when using the Facebook SDK together with [Guzzle](https://github.com/guzzle/guzzle) 6.x. php-graph-sdk v5.x only works with Guzzle 5.x out of the box. However, [there is a workaround to make it work with Guzzle 6.x](https://www.sammyk.me/how-to-inject-your-own-http-client-in-the-facebook-php-sdk-v5#writing-a-guzzle-6-http-client-implementation-from-scratch).
-
-## Upgrading to v5.x
-
-Upgrading from v4.x? Facebook PHP SDK v5.x introduced breaking changes. Please [read the upgrade guide](https://www.sammyk.me/upgrading-the-facebook-php-sdk-from-v4-to-v5) before upgrading.
-
-## Usage
-
-> **Note:** This version of the Facebook SDK for PHP requires PHP 5.4 or greater.
-
-Simple GET example of a user's profile.
-
-```php
-require_once __DIR__ . '/vendor/autoload.php'; // change path as needed
-
-$fb = new \Facebook\Facebook([
-  'app_id' => '{app-id}',
-  'app_secret' => '{app-secret}',
-  'default_graph_version' => 'v2.10',
-  //'default_access_token' => '{access-token}', // optional
-]);
-
-// Use one of the helper classes to get a Facebook\Authentication\AccessToken entity.
-//   $helper = $fb->getRedirectLoginHelper();
-//   $helper = $fb->getJavaScriptHelper();
-//   $helper = $fb->getCanvasHelper();
-//   $helper = $fb->getPageTabHelper();
-
-try {
-  // Get the \Facebook\GraphNodes\GraphUser object for the current user.
-  // If you provided a 'default_access_token', the '{access-token}' is optional.
-  $response = $fb->get('/me', '{access-token}');
-} catch(\Facebook\Exceptions\FacebookResponseException $e) {
-  // When Graph returns an error
-  echo 'Graph returned an error: ' . $e->getMessage();
-  exit;
-} catch(\Facebook\Exceptions\FacebookSDKException $e) {
-  // When validation fails or other local issues
-  echo 'Facebook SDK returned an error: ' . $e->getMessage();
-  exit;
-}
-
-$me = $response->getGraphUser();
-echo 'Logged in as ' . $me->getName();
-```
-
-Complete documentation, installation instructions, and examples are available [here](docs/).
-
-## Tests
-
-1. [Composer](https://getcomposer.org/) is a prerequisite for running the tests. Install composer globally, then run `composer install` to install required files.
-2. Create a test app on [Facebook Developers](https://developers.facebook.com), then create `tests/FacebookTestCredentials.php` from `tests/FacebookTestCredentials.php.dist` and edit it to add your credentials.
-3. The tests can be executed by running this command from the root directory:
-
-```bash
-$ ./vendor/bin/phpunit
-```
-
-By default the tests will send live HTTP requests to the Graph API. If you are without an internet connection you can skip these tests by excluding the `integration` group.
-
-```bash
-$ ./vendor/bin/phpunit --exclude-group integration
-```
