Flash the Raspberry Pi Image onto an SD Card
Download the latest Mothbox Image to your computer. You may need an unzipping software like 7zip to unzip the image after you download it.
Download Software to flash the the Image. You can use the traditional, Raspberry Pi Imager, or I often use Win32DiskImager.
Get an SD card (at least 16GB). Connect it to your computer.
Start the Imaging software. If you are using Raspberry Pi Imager, click “Choose OS.” Then scroll all the way down to choose “Use Custom.” Click “Choose Storage” and choose the SD card you have connected. Click “Next.”
If it asks you to apply customization options, just click no.
Now it will start flashing your SD card. This should take about 5-10 mins.
Insert SD Card into Pi
Put this newly flashed SD card into the bottom of your Pi and push it all the way in.
