cat <<EOF > /etc/network/interfaces.d/wlan0
allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
EOF

4. Create a configuration file with the relevant ssid:

cat <<EOF > /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/run/wpa_supplicant
update_config=1
network={
    ssid="MYSSID"
    psk="passphrase" 
}
EOF

5. Make sure it works:

Restart your device and it should connect to the wireless network. You can check it by running the command $ iwconfig . If it doesn't, repeat above steps or get help from an adult.

GUI On Debian

There is an option with the Debian image, up to the user, to work with a GUI like Weston, GNOME and etc.
For applying this option do the following steps:

First, connect your device to a screen using the working output (HDMI / uHDMI).

For working with Weston GUI:

1. Install the Weston package.

   $ sudo apt install weston

2. Make a directory for the output of the Weston GUI.

   $ mkdir /your/directory/location

3. Give permissions to this directory.

    $ chmod 0700 /your/directory/location

4. Set the XDG_RUNTIME_DIR env param to your directory.

   $ export XDG_RUNTIME_DIR=/your/directory/location

5. Run Weston.

   $ weston

For working with GNOME GUI on top of Xorg:

1. Install Xorg.

   $ sudo apt install xorg

2. Install your desired gnome.

   $ sudo apt install gnome-session

   NOTE: ‘gnome-session’ is an example of gnome that we can work with, you can replace the ‘session' with another GNOME extention.

3. Start your GNOME GUI.

   $ sudo systemctl start gdm

   • For logging in you need a user on your device to log into it. You can create one before step 3 by this command (replace the ‘username’ with name that you want) :

   $ sudo adduser username

   • You can jump between GUIs that you install (like gnome-session) by the setting button that locates in the down right corner of the home screen.
