I might occasionally fix or add something I notice is missing.
I'm also rather new to wiki markup (though good in HTML/code in general) so I might at time stumble or use some markup the wrong way. It's a learning experience.
Wiki markup hates preformatted text blocks in numbered lists. Specifically the newlines in the preformatted text blocks interferes with the wiki markup for the numbered lists so that a new list is created underneath the preformatted text block. Use pure HTML instead since it's much easier to work with and gets the job done the right way.
