 We use [prettier](https://prettier.io/) formatter to format our typescript code. The easiest way to use [prettier](https://prettier.io/) is through the [prettier-vscode](https://marketplace.visualstudio.com/items?itemName=esbenp.prettier-vscode) VS Code extensions. You are also advised to use [eslint](https://eslint.org/) for linting your code before.
 
+## Provide translations
+
+The local App translations (i.e. header and footer) are provided through [Crowdin](https://crowdin.com/project/github-emoji-picker). Please check out https://crowdin.com/project/github-emoji-picker if you want to add a card translation. The Emoji-Picker translations are handled by the [Emoji Mart package](https://github.com/missive/emoji-mart). If you want to translate parts of the picker, please open an issue at https://github.com/missive/emoji-mart/issues.
