New Infopage: First steps in Pinegrow and HTML for absolute beginners

I created a help page for absolute beginners to help them doing the first steps in Pinegrow and HTML. The new help page explains the basics of HTML and how to work in Pinegrow. You will learn how a website is built and how to use HTML elements. An example website is used to describe its structure and styling, so that absolute beginners can take their first steps in Pinegrow.
