A typical directory structure for three language packages follows:
├── de_DE
│ ├── composer.json
│ ├── language.xml
│ ├── LICENSE_AFL.txt
│ ├── LICENSE.txt
│ └── registration.php
├── en_US
│ ├── composer.json
│ ├── language.xml
│ ├── LICENSE_AFL.txt
│ ├── LICENSE.txt
│ └── registration.php
├── pt_BR
│ ├── composer.json
│ ├── language.xml
│ ├── LICENSE_AFL.txt
│ ├── LICENSE.txt
│ └── registration.php
The only required directory for a language package is the top-level directory. Although not required, we recommend that the directory name match the ISO{:target="_blank"} code to identify the locale.
For more information about language packages, see Translation dictionaries and language packages.
