Documentation subpages[edit]


Like many other MediaWiki extensions, ChessBrowser's user interface legends and messages can be translated at translatewiki.

A particular issue to look out for when localising ChessBrowser are rank and file notation and legends. Many world languages use European numbers (1–8) for rank, and Latin letters (a–h) for file. In some languages, use of different numerals or letters is common. If your language uses different characters, translate the extension with optional messages enabled. No need to do it for languages where common chess notation is the default (1-8 / a-h). This affects algebraic notation display, as well as board display rank and file legends.
