Bitcoin core client - Altcoin implementation question

[Cryptoshi]

On the old version of Bitcoin when you downloaded the wallet it was a zip file and you had to extract it and then run it after clicking the extracted bitcoin qt. But the new Bitcoin you are able just download the client and run it without extracting anything. How do I do this? I have a cryptocurrency I'm making but it's currently a zip file once you download it. How do I make it able to be run instantly after being downloaded like the new bitcoin wallet client? Please don't troll me if you think I'm a noob or anything it's just a simple question.
