<h2>How to use</h2>
<ol>
<li>Select your camera.</li>
<li>Hit start</li>
<li>
Wait for the video to load side-by-side. *If it does not auto-load within 20s, refresh and try again.*
</li>
<li>
Stats will be printed to screen, along with graphs visualizing the most important metrics. You can also hold CTRL (cmd) + Click on the video to access even more stats.
</li>
<li>
Bitrate, Buffer delay, and packet loss are important connection quality metrics. Monitor them for at least a minute.
</li>
<li>
Change the video bitrate by pressing the buttons below the video. It should approach 6000-kbps if the network allows.
</li>
<li>
Good packet loss will not exceed 0.1% and bad packet loss will exceed 1%. You can try testing against different global regions with the drop-down menu below.
</li>
<li>
Check out <a href="https://youtu.be/je2ljlvLzlY" target="_blank" style='color:#DEF;'>this Youtube video</a> for more details and solutions to reduce packet loss if suffering from any.
