How to change SSID and KEY after installation

Hi,
I have installed Dietpi on a raspi-3b. The follow is the configration for network.

# >> Networking Options -----------------------------
#If both Ethernet and Wifi are enabled, Wifi will take priority and Ethernet will be disabled.
#   1=enabled
Ethernet_Enabled=1
Wifi_Enabled=1

#Enter your Wifi details below, if applicable (Case Sensitive).
Wifi_SSID=Apple
Wifi_KEY=123123

#Enter your Static Network details below, if applicable.
Use_Static=1
Static_IP=192.168.31.202
Static_Mask=255.255.255.0
Static_Gateway=192.168.31.1
Static_DNS=192.168.31.1

Now, I have changed the WIFI SSID to “Orange”, and changed the KEY to “456456”.
How could I change the configration on Raspi for wifi connection?

dietpi-config

Change thru the network option in there
