Where to put Static Meshes?

[DidibaDEV]

I'm a beginner, so this will feel stupid (and I feel dumb for asking), but where are Static Meshes and Textures supposed to go?

The readme example shows an Art folder that also has Animations and Sounds, so I guessed there at first. But then, the readme also mentions an Environment folder later on ("Want to view only static mesh in Environment/Rocks/?").

So, is it Content/Art/Subfolder or Content/Environment/Subfolder?

Also, I suggest that it gets clarified in the readme for newbies like me.
