# If you have a complex configuration with numerous options or if you want to keep a clear configuration changes history,
# you can specify the options in a configuration file :
selenium-standalone install --config=/path/to/config.json
selenium-standalone start --config=./config/seleniumConfig.js

# prevent killing selenium process before start
selenium-standalone start --processKiller=false

# install or start only certain driver
selenium-standalone install --onlyDriver=chrome
selenium-standalone start --onlyDriver=chrome

```

Config file can be a JSON file or a [module file](https://nodejs.org/api/modules.html#modules_file_modules) that exports options as an object:

```js
module.exports = {
  drivers: {
    chrome: {
      version: '87.0.4280.20',
      arch: process.arch,
      baseURL: 'https://chromedriver.storage.googleapis.com'
    },
  },
}
```
