Localizing Hackasaurus curriculum and tools is a great way to contribute to the project.
Both the goggles and the website can be localized using localize.mozilla.org. The goggles can be localized by translating webxray.pot, while the website uses default.pot. To preview the results of your localization work on a staging version of the website and tools, read this post.
If you have any problems, or if your locale isn't listed on localize.mozilla.org, please feel free to join our Google Group or
#hackasaurus on IRC and let us know.
Unfortunately, we have yet to make it easy to localize the Hacktivity Kit and related PDFs. We're working on it, though!
