Raspbian Installation - Step 1 - Download NOOBS

In order to make the Raspberry Pi board work, an Operating System needs to be installed on it. For people who are new to the world of Pi boards, NOOBS (New Out of Box Software) makes is very easy to install one of your choice. You can either buy an SD card pre-loaded with NOOBS or download one from https://www.raspberrypi.org/downloads/noobs/ as a first step

Raspbian Installation - Step 3 - Copy NOOBS files on the SD card

Extract the NOOBS zip file in computer and copy only the NOOBS files in the formatted SD card.

Raspbian Installation - Step 4 - Boot the Raspberry Pi

Insert the SD card in the card slot provided underneath the Raspberry Pi after copying the NOOBS files in it. Boot the Raspberry Pi board to allow NOOBS to guide you through the installation of operating system like Raspbian or LibreELEC, OSMC etc.

Setups and updates after Raspbian installation

Make sure you run following command in terminal once after you install Raspbian OS and reboot to a desktop to update firmware of the Pi board:
