I have installed and used Ubuntu, and now I want to try the GNOME desktop environment.
I don't know where to start. Could you give me some guidance?
Thanks!

Open a terminal and first of all fetch the latest package informations via
sudo apt update
Then install gnome-shell via the following command
sudo apt install ubuntu-gnome-desktop
If that finished, logout and back in the login-dialog (most likely lightdm) choose your session type and relogin to a new session - this time using Gnome.

You'll find some documentation for the gnome project here.
Go to the terminal and type this command:
sudo apt-get install ubuntu-gnome-desktop
Logoff, then select the Gnome Desktop at the login screen.
