 As soon as the translation is finished, the branch localisation will be merged into the [`main`](https://github.com/NFDI4Chem/knowledge_base/tree/main) branch. The public website will subsequently be automatically rebuilt with the English sources and the translations downloaded from Crowdin.
 
+If you just want to contribute to the German translation, feel free to make the necessary changes via Crowdin. When you are done, the site will be rebuilt using the existing English source and the updates from Crowdin.
