All of the articles and cheat sheets on this site have so far only been created in English. Much as I'd like to offer them in a variety of language, I unfortunately lack the linguistic skills to be able to do so. Fortunately, there are some multilingual saints out there who have taken the time to translate various parts of this site into other languages.
Where translations exist (and I know about them) they are now linked to from the bottom of each article. If you know of a translation I'm missing (or would like to translate something into a different language) please e-mail me.
Update: I've added the "hreflang" attribute to links that point to translations.
