 There are two different ways of adding a new dictionary of messages to a certain locale:

 Just `import`/`require` your locale `.json` files and pass them to the [`addMessages(locale, dict)`](/docs/Methods.md#addmessage) method.

 A more performant way to load your dictionaries is to register `loader` methods. This way, only the files registered to the current locale will be loaded. A `loader` is a method which must return a `Promise` that resolves to a `JSON` object. A [`$locale`](/kaisermann/svelte-i18n/Locale) value change will automatically load the registered loaders for the new locale.

 After populating your [`$dictionary`](/docs/Dictionary.md) with [`addMessages()`](/docs/Methods.md#addmessages) or registering loaders via [`register()`](/docs/Methods.md#register), you are ready to bootstrap the library. You can use [`init()`](/docs/Methods.md#init) to define the fallback locale, initial locale and other options of your app.
