Updated in July 2019. SharePoint Online from Scratch gives hands-on instructions on how to practically make use of a SharePoint tenant for an organization, or parts thereof. It is almost entirely no-code. Even if SharePoint Online from Scratch primarily is a handbook, explanations on how SharePoint works are mixed into the instructions. SharePoint Online is an ever changing platform, so the author's aim is to give a deeper understanding of how to take advantage of SharePoint at the same time as giving practical advice. The fifth edition is updated with more about the modern experience interface, sites and pages. It covers changes in SharePoint Online up to July 2019.
