Great question! We've not yet implemented the localization system but it's something we're going to be looking at once we have finalized all the in game dialog and encounters.
We've had a lot of offers by fans to help with the translation and we could definitely get you all involved when that time comes. We will probably identify some languages to get "professionally" translated and then post spreadsheets where fans can provide translations (or work together on them) for other languages.
What language would you be interested in helping with?
