Download the blender file and the txt file and move them to your asset browser folder. You can specify in blender in the Preferences where this asset browser folder should be located.

You will find the asset browser as a separate window in blender, as well as 3D viewport, shader editor, compositor and so on.

In the Asset Browser, you'll find categories for Compositing Nodes, World Shading Nodes, and Geometry Nodes.

The assets move around the point 0,0,0. That means the camera so should be there. To do this, you can simply select your camera, and then use alt G to move the camera to the point 0,0,0. Now it should look at the Y axis. For this you can press alt R and then R 90 X. This will make the camera look at the Y axis.  In the camera settings I used a deep focal length for my videos, mostly 15mm. This gives a great look for visualizer clips!
