 ## Snippet file structure
 
 Shopware 6 automatically loads your snippet files when a standard file structure and a naming convention are followed.
-To do so, store your snippet files in the `<extension root>/src/Resources/snippet/` directory of your extension.
+To do so, store your snippet files in the `<extension root>/src/Resources/snippet/` directory of your plugin or `<extension root>/Resources/snippet/` for your app or theme.
 Also, you can use further subdirectories if you want to.
 Use `<name>.<locale>` as the naming pattern for the file.
 The name can be freely defined, while the locale **must** map to the ISO string of the supported locale in this snippet file - for example `example.de-DE.json`.
 More precisely, the ISO string is a combination of "ISO 639-1" language codes and "ISO 3166-1 alpha-2" country codes.
-Later this will be converted to the ICU format (`de_DE`), which is also used by [Symfony](https://symfony.com/doc/current/reference/constraints/Locale.html).

 In case you want to provide base translations (ship translations for a whole new language), indicate it with the suffix `.base` in your file name.
 Now the filename convention to be followed looks like this `<name>.<locale>.base.json` - for example, `example.de-AT.base.json`.
