How to put out over the air updates to my game?

I almost done with my game and i dont want to out it on steam or other game marketplaces jsut yet, but i want to put it on my website. I also plan on making updates to the game, but i dont know how i would update the game without having the user reinstall the new version from my website. How do i do this?

You would need to make a system to download and install updates, like a launcher. I don’t know of anything specifically for Unreal, but there are systems like that for Unity that can actually be used for any program so if you wanted you could use one of those with Unity to make a Launcher/Patcher for your Unreal game. The only thing else you would need is hosting for the patch files.
