The Locale Switcher app provides a component capable of changing the current language of your store.

1. Add the Locale Switcher app to your theme's dependencies in the manifest.json file:

 "dependencies": {
+  "vtex.locale-switcher": "0.x"
 }

2. Add the locale-switcher block to your header. For example:

"header-row#desktop": {
  "children": [
    // (...)
    "locale-switcher",
    "login",
    "minicart.v2"
  ]
},

3. Open a ticket to our support team in order to adjust your store's binding with the desired languages.

*Caution: The third step is mandatory. If no ticket is opened requiring the desired languages, the selection list may not appear on the Locale Switcher component.*

In order to apply CSS customizations in this and other blocks, follow the instructions given in the recipe on Using CSS Handles for store customization.
