 ### Options
 Options are set via [environment variables](https://kinsta.com/knowledgebase/what-is-an-environment-variable/) which can be set in many ways and allow for flexible configuration.

 #### Other ways to set options
 On Linux/macOS you can prefix the variables you want to set, for example `EMAIL=foo@bar.baz SHOW=1 node epic-games` will show the browser and skip asking you for your login email.
 For Docker you can pass variables using `-e VAR=VAL`, for example `docker run -e EMAIL=foo@bar.baz ...` or using `--env-file` (see [docs](https://docs.docker.com/engine/reference/commandline/run/#set-environment-variables--e---env---env-file)). If you are using [docker compose](https://docs.docker.com/compose/environment-variables/), you can put them in the `environment:` section.
