Added a How-to Video to my website

Minor update about Letternerd (A website for creating letters and letter cards for all occasions).

I added a how-to video to the website to show users how to use the platform. The platform is straightforward and easy to use. I only added it because it is if other people that may just be interested in scrolling through the website while not actually using it. Have anyone added video and seen a boost in their conversion rate before? and also which one is better? A music background video or voice-over video?

P.S The website is letternerd.com
