 ## 🌎 Translations
 
 Translations for text within BookStack is managed through the [BookStack project on Crowdin](https://crowdin.com/project/bookstack). Some strings have colon-prefixed variables in such as `:userName`. Leave these values as they are as they will be replaced at run-time. Crowdin is the preferred way to provide translations, otherwise the raw translations files can be found within the `resources/lang` path.
