You can enter one or more extension keys, separated by commas. In addition, you can use a wildcard at the end to exclude extensions that begin with a specific extension key. Some examples: `my_extension` Excludes the extension with the key `my_extension`. `some_extension, another_extension` Excludes the extensions with the keys `some_extension` and `another_extension`. `myproject_*` Excludes the extensions, for example, with the keys `myproject_site`, `myproject_video` or `myproject_download`. After saving you can check your configuration with the :ref:`language:update ` command. The excluded extensions should not be listed.
