OS Introduction
In the previous chapter, we powered on the Walnut Pi and logged into the system. The main difference between the Desktop and Server editions: you can think of the Server edition as the Desktop edition with the desktop removed. Therefore, standard Linux commands and configuration instructions are generally universal across both systems.
The first boot of the Walnut Pi Desktop Edition takes quite a while—approximately several minutes—as it needs to initialize software and services. Please be patient and wait for the system desktop to appear. Subsequent boots will be much faster, taking only about tens of seconds.

Browser
The Walnut Pi system comes pre-installed with Chromium (Google Chrome Mini). It is located as the first item in the Launch Bar and works just like any regular computer browser.

File Manager
The File Manager is the second item in the Launch Bar. Opening it reveals all files on the Walnut Pi, which are stored on the SD card.

System Settings
System Settings can be found in the Start Menu. Users can configure various Walnut Pi system features according to their needs.

System Version Query
You can check the current Walnut Pi system version with the following command:
cat /etc/WalnutPi-release

OTA System Update
You can fetch upgrade packages from the Walnut Pi cloud server via a command, enabling remote system upgrades without the need to re-burn the image each time.
OTA update command:
sudo wpi-update
