How do I make a skybox?

[Sovario]

I've been searching for MANY tutorials and no success. I'm making a skybox, or trying to, and I need help. I have a custom textures folder for other textures I needed, and that's where my skybox is placed. I really need a VERY in-depth explanation cuz my map will stay leaked and unable to be tested if I can't do that.

You got this all wrong. Sorry. I have all the pictures of the skybox, I just need to insert them now. I don't know how.

And I also want the sun to beam down so there is some light.

As well, when I test it out, I see grey instead of the textures. What do I do with the textures?
