Examples don't work

[dark-passages]

All the example files are missing the line:

*** Settings ***
Library             SeleniumLibrary

Without it none of the examples work.
As a beginner it's already very hard to get things to work in Robot Framework with the terrible documentation everywhere, but good examples help, but they are even harder to find. Like this relative complex example, why the need to split the example in 5 files? Do I need all the files? (yes, I need a .robot and the .xlsx file, but the other files? DataDriven.robot, invalidLogins.robot, login_resources.robot and validTest.robot?

Also the links to the example files is not correct, it leads to the main folder, not the examples folder. (and why make 2 links that both lead to the same folder?)
