How to install unity sources?

Question

Unity

I wanted to look at some ready-made sources on unity, went to the store, found a free source, went to unity, created a new empty project, went to the Asset Store, chose the one I needed, downloaded and imported.
as a result, Assets can be seen all loaded and present, but the hierarchy is completely empty, respectively, and there is nothing to run to see what this source shows ...
How to install it correctly?

Answer 1

Not all "sources" (which are actually assets, not sources) can contain something that will be in the hierarchy.
And if they do, then you need to open the scene that this asset added. Well, or drag the prefab - in each case in different ways.
