Q3: I want to add some sourced information with references but don't understand the referencing style.
A3: This article's established referencing is a specific type of Harvard style citations, making use of anchored references, using the hashtag symbol to anchor the references to the cited sources. The nomenclature looks like:
<ref>[[#abc| Author name, 2000]], p.123</ref>...placed as an inline citation within the text, which then creates a shortened footnote in the References section.
{{cite book |last=Smith |first=Alex |title=book title |year=2000 |publisher=publisher name |ref=abc }}...placed in the Bibliography section.
