Adding a video to your Bark profile is very straight forward, all you need is the URL to your video on YouTube and you can then link it in.
Start by clicking 'Upload video'.
You'll then be presented with an option to enter your YouTube video URL.
To do this, simply copy and paste the relevant URL for your YouTube video.
It will then appear in the video section as seen in the image below. Just remember to press 'save' once you're happy.
