To use this component on your Framer site, all you need to do is to copy and paste it onto your page.
When using it as a background, I recommend setting it to absolute position, and using the pins to pin it to all sides of the parent frame with 0 values.
The component has a bunch of properties on the right panel that you can use for customization. Change the color, and how the effects plays or looks. You can enable or disable the animation depending on what you need.
