# Mandatory plugins
If you rely on some plugins, you can define mandatory plugins by adding `plugin.mandatory` setting to the `config/elasticsearch.yml` file, for example:
```yaml
plugin.mandatory: analysis-icu,lang-js
```

For safety reasons, a node will not start if it is missing a mandatory plugin.
