 1. Run `script/test` and make sure there are no failures with your translation files. Note that you may need to fix broken links.
 1. Send a pull request. (You may send a pull request before all steps above are complete: e.g., you may want to ask for help with translations, or getting tests to pass. However your pull request will not be merged until all steps above are complete.)
 
-Completing an initial translation of the whole site is a fairly large task. One way to break that task up is to work with other translators through pull requests on your fork. Example: [pull requests on fork for German translation](https://github.com/katrinleinweber/opensource.guide/pulls?q=is%3Apr+is%3Aclosed) and corresponding [initial pull request for German translation](https://github.com/github/opensource.guide/pull/577) on this repository.
