Formatting Wookieepedia articles is a bit different from writing on a standard word processor. Instead of a strict ("what you see is what you get") approach, Wookieepedia uses text codes to create particular elements of the page (e.g. headings). This "language" is known as Wikicode (or Wiki-markup) and is designed for ease of editing.
Headings and subheadings are an easy way to improve the organization of an article. If you can see two or more distinct topics being discussed, you can break up the article by inserting a heading for each section.
If an article has at least four headings, a table of contents will automatically be generated. Try creating a heading in the sandbox. It will be added automatically to the table of contents for the page, assuming three others already exist.
It is a Wookieepedia convention to mark in bold the names of an article's subject when they are first mentioned in the article. For example, the article Mount Sorrow begins:
Mount Sorrow was a mountain on the Forest Moon of Endor.
Another Wookieepedia convention is to italicize book, movie, album, and computer/video game titles. If the first mention of the subject of an article is also a book or movie title then bold italics is used. For example, the article Star Wars: Republic starts:
Star Wars: Republic was a series of comics published by Dark Horse Comics.
It is usually preferred that the names of papers (e.g. a scientific article), chapters (e.g. in a book), songs, or television episodes are mentioned "in quotes" rather than being italicised. If the first mention of the subject of an article is also one of these things, then it is "emboldened and quoted." For example, the article "The Season Scepter" begins:
"The Season Scepter" is the twenty-sixth episode in the Star Wars: Ewoks animated television series, and the thirteenth episode in season two.
