An acquaintance needed a video kiosk that plays looping videos for an exposition booth. Since I have a bunch of Raspberry Pis lying around, I figured that it would be the perfect use case for using one of them.
Let's assume we start from scratch, with a unflashed, brand new SD card and your Raspberry Pi.
Installing the OS
Install a version of Raspbian that includes the desktop. You can head over to : https://www.raspberrypi.org/downloads/raspbian/ and follow the instructions.
Once the image is downloaded, you can burn it to your SD card with tools like Etcher (https://www.balena.io/etcher/)
