Update 21 May 2022: I need to work on reformatting this due to now using Markdown. The content is still here though!

[N.B.: This is a guest piece kindly provided by gom (Mastodon and email is below as well), for whom I offered to publish this guide on my site. Any updates will come from them whenever necessary; all I have done is to format it as close to their original HTML code as possible and kept anchors intact. -grey]
