The Style Guide is an ongoing attempt to build a reference resource for use by authors of Star Army articles and canon.
These are the key points for wiki articles:
Headers provide structure for wiki pages and divide them into index and easily-read sections.
This section covers what kind of content should and should not be in the wiki page.
As of 7/7/2018 the first image on a wiki article must be an image of the actual subject of the article. Don't use corporate logos, etc, as the first image on the page. This helps with indexing and page previews.
Please only use file names that make sense and are easily read. Badly named images are difficult to find, and they make understanding the image difficult or impossible for blind and low-vision roleplayers who have to rely on the text being read to them.
It is also nice, but not required, to credit the artist in the file name if it was a commission (e.g. hanako_by_zairyo.png). You can also credit artists on the pages the image is used on, or in the image itself if it doesn't get in the way of the subject.
