-If the key does not exist, then i18n will return the key string to caller. For instance, when key name is `hi` and it does not exist in locale file, simply return `hi` as output.
+- The first locale you load to the module is considered as **default locale**.
+- When matching non-default locale and didn't find the string, i18n will have a second try on default locale.
+- If i18n still cannot find string in the default locale, raw string will be returned. For instance, when the string is `hi` and it does not exist in locale file, simply return `hi` as output.
