How do I make a sky using skybox?

I am new to all this and I was wondering because on someones tutorial, he had like blue sky and sunset but when I click on it, there are things like underwater and low hanging dream and things like that.

Please help! Thanks.

How a skybox is integrated into Unity is explained in the reference manual: Skybox

A little more info can be found in the main manual: How do I make a Skybox

For rending the skybox, there's a couple of possibilities. Personally, I'm using Vue by e-on Software. There are a couple of tutorials on how to create the Skybox textures with Vue, e.g. Skybox Tutorial. This is for XNA but that doesn't really make a difference if you understand how to use Skyboxes in Unity.
