+            We really appreciate you taking the time to improve our translations.
+            
+            However we use a translation tool called [Crowdin](https://crowdin.com/) to help manage our localization efforts across many different languages. Our translations can only be updated using Crowdin, so we'll have to close this PR, but would really appreciate if you'd consider joining our awesome translation community over at Crowdin.
