The wiki has a number of known languages. See TranslatingPages for some background.
Here’s what to do if you want to translate a page such as our SandBox:
- Visit SandBox
- Scroll to the bottom and click the Add Translation link
- Pick a language such as Deutsch (only languages without existing translation links are offered…)
- Choose the name of the translated page name, eg. SandKasten
- Click the Go! button
- This will add the translation link [[de:SandKasten]] to the SandBox page, telling the wiki that SandKasten is a translation of SandBox
- You will end up editing the SandKasten page
