How to download minecraft?

I tried downloading minecraft but you have to download a bunch of stuff and when i download it it still doesn't work and just slows my computer down

Go to the Minecraft website and click "Get Minecraft" You will be asked to create a mojang account. After that you will be asked to reedem a code or buy it. Then you can dowload it. Double-click on the Minecraft launcher to launch the application. The first time you do this, the launcher will install the necessary files onto your computer.

Make sure you have Java updated and installed. Just follow what the other two people said.
