1.- Installation of the Operating System in the microSD

We will start by downloading the operating system from the official website:

https://www.raspberrypi.org/downloads/raspbian

We can use any of the 2 available options (desktop or Lite), although I usually use the Lite version (without graphic interface) because with the console it is more than enough.

⊗ Nota: Once you have downloaded the file, you will have to unzip it (it comes in ZIP format)

The RsPi uses a microSD card as if it were the hard disk of a computer. We can use a 4Gb microSD card but surely for price and availability, the best option will be 8Gb. 

To copy the downloaded image on the card, obviously you will need a microSD reader on the PC and the Win32 Disk Imager program that you can download for free from:

https://sourceforge.net/projects/win32diskimager/files/latest/download

Once the program is installed and with a microSD card in your reader, the copy is very simple. You must indicate the place and the name of the file (operating system that you downloaded and unzipped), the unit where the microSD card is and finally press the write button. In a few minutes you will have ready the microSD card with the operating system loaded, then it is time to put the card in the RsPi and turn it on.

It is advisable that when you have finished running all the software, that you use this Win32 Disk Image utility to backup the microSD card. In this case you will indicate the place “Image File” the place where you will save the image, the unit where the microSD card is and in this case you will press the Read button. With this you will always have a backup and a fast reverse
