 ## Localization
+
 ### Supported locales
+
 [Apple locales list](https://www.apple.com/itunes/marketing-on-itunes/identity-guidelines.html#itunes-store-badges#LocalizedBadges)
 
 [Google locales list](https://github.com/yjb94/google-play-badge-svg/tree/master/img)
 
 ### Localization tip
+
 - iOS uses full code of their locale. (ex. en-us) and google uses short code of their locale(ex. en). So if you want your badge in only one store, you can customize it anyway.
 
 ## Badge Guidelines
+
 please note that you have to follow the guidelines below
