Technical requirements
You need either a LaTeX installation on your computer, or you can use Overleaf. You can edit and compile all examples online on the book's web page: https://latexguide.org/chapter-03.
The code is also available on GitHub: https://github.com/PacktPublishing/LaTeX-Beginner-s-Guide-2nd-Edition-/tree/main/Chapter_03_-_Designing_Pages.
In this chapter, we will use the following LaTeX packages: babel, blindtext, fancyhdr, geometry, and setspace. If you don't work online, make sure you have them installed if you don't have a full LaTeX installation. We'll also talk about the packages bigfoot, endnotes, footmisc, lipsum, manyfoot, multicol, safefnmark, and scrlayer-scrpage, which you may optionally use.
You can find package information on CTAN at https://ctan.org/pkg/<packagename>, and documentation at https://texdoc.org/pkg/<packagename>.
