Alteryx Designer: SharePoint List Input Tool

[OkinoLeiba]

Can someone walk me through setting up the SharePoint List Input Tool, and please speak to me as I am a child.

It is my understanding that there are three ways to setup the SharePoint List Input Tool based on the SharePoint Version (2013/2016, Online/Office 365, and App Only Authentication). Each method requires a User ID, E-mail Address, or Client ID. With the User ID is the documentation referring to my machines domain name on my network or the SharePoint domain name (company name.sharepoint.com) and Username. Is there something that I am missing? Does SharePoint URL need to be in a specific format?
