Procedures
Step 1
To download NOOBS from your PC, you can choose NOOBS or NOOBS LITE - the only difference is that
there is a built-in offline Raspbian installer in NOOBS, while the NOOBS LITE can only be operated online.
Here, you are suggested to use the former. Here is the download address of Noobs:

Step 2
Plug in the Micro SD reader and format the Micro SD card with the SD Formatter
(https://www.sdcard.org/downloads/formatter/index.html). If there are some important files in the Micro
SD card, please backup them first.
