Raspbian fresh images come in UK English language, this includes QWERTY keyboard, so people with other keyboards may need to change it.
The easy way to do it is by modifying directly the default configuration file.
From command line, type:
sudo nano /etc/default/keyboard
In the line:
Change gb to the language/country that you want, for example France AZERTY is fr.
You can find your country code here: https://countrycode.org/
Now the new keyboard layout is activated.
