 ## Quickstart
 First of all, you need to include the package in your code:
-``` php
+```php
 require 'vendor/autoload.php'; // path to the autoload file
 ```
 
 ### Configuration
 This package will autodetect FFmpeg and FFprobe binaries. If you want to give binary paths explicitly, you can pass an array as configuration. A Psr\Logger\LoggerInterface can also be passed to log binary executions.

 #### 1. From an FFmpeg supported resource
 You can pass a local path of video(or a supported resource) to the `open` method:

 See **[FFmpeg Protocols Documentation](https://ffmpeg.org/ffmpeg-protocols.html)** for more information about supported resources such as HTTP, FTP, and etc.

-``` php

 No, IOS does not have native support for DASH. Although there are some libraries such as **[Viblast](https://github.com/Viblast/ios-player-sdk)** and **[MPEGDASH-iOS-Player](https://github.com/MPEGDASHPlayer/MPEGDASH-iOS-Player)** to support this technique, I have never tested them. So maybe some of them will not work properly.
