This step is optional (only about half of artists do this), if you don’t want to do it now you can always come back and do this later.
When fans arrive at your page for the first time, they will see your Community description and the tiers that you are offering. You have the option to include a video explaining what the community is and to get people excited.
Why add a video?
Some fans may not believe it is really you behind this community, and this will prove to them it is. Some fans may be on the fence about joining a paid tier, but if you are genuinely enthused in your video it may convince them to spend the money! Overall, it just makes your page look better and feel more personal to you.
