/**
* <h2>Prerequisites on using Skylink</h2>
* Before using any Skylink functionalities, you will need to authenticate your App Key using
* the <a href="#method_init">`init()` method</a>.
*
* To manage or create App Keys, you may access the [Skylink Developer Portal here](https://console.temasys.io).
*
* To view the list of supported browsers, visit [the list here](
* https://github.com/Temasys/SkylinkJS#supported-browsers).
*
* Here are some articles to help you get started:
* - [How to setup a simple video call](https://temasys.com.sg/getting-started-with-webrtc-and-skylinkjs/)
* - [How to setup screensharing](https://temasys.com.sg/screensharing-with-skylinkjs/)
* - [How to create a chatroom like feature](https://temasys.com.sg/building-a-simple-peer-to-peer-webrtc-chat/)
*
* Here are some demos you may use to aid your development:
* - Getaroom.io [[Demo](https://getaroom.io) / [Source code](https://github.com/Temasys/getaroom)]
* - Creating a component [[Link](https://github.com/Temasys/skylink-call-button)]
*
* You may see the example below in the <a href="#">Constructor tab</a> to have a general idea how event subscription
* and the ordering of <a href="#method_init"><code>init()</code></a> and
* <a href="#method_joinRoom"><code>joinRoom()</code></a> methods should be called.
*
* If you have any issues, you may find answers to your questions in the FAQ section on [our support portal](
* http://support.temasys.io), asks questions, request features or raise bug tickets as well.
*
