Due to the size of the files the files in this folder are likely to
go offline after a newer version has been uploaded.
By default the user "pi" has a password "raspberry".
SSH server is active, GUI/X11 has been switched off to
leave more RAM for web applications. sudo su escalates
the "pi" to "root" without any password. raspi-config
allows the "root" to switch the GUI/X11 back on.
The GUI/X11 will not start immediately after the raspi-config
exits, but after a reboot.
