If you're in doubt about any of the names of these environment variables, just check the `--help` for the subcommand you're using.
!!! tip "Environment variable arrays"
If you need to use an environment variable to set a configuration option that accepts an array, provide each value in a comma-separated list.
For example, `instance-languages` may be set in the config.yaml file as an array like so: `["nl", "de", "fr", "en"]`. To set the same values as an environment variable, use: `GTS_INSTANCE_LANGUAGES="nl,de,fr,en"`
### Command Line Flags
Finally, you can set configuration values using command-line flags, which you pass directly when you're running a `gotosocial` command. For example, instead of setting `media-image-max-size` in your config.yaml, or with an environment variable, you can pass the value directly through the command line:

!!! info "Optional configuration"
There are many other configuration options documented in the config.yaml file, which you can use to further customize the behavior of your GoToSocial instance. These use sensible defaults where possible, so you don't necessarily need to make any changes to them right now, but here are a few you may be interested in:
- `GTS_INSTANCE_LANGUAGES`: array of [BCP47 language tags](https://en.wikipedia.org/wiki/IETF_language_tag) which determines the preferred languages of your instance.
- `GTS_MEDIA_REMOTE_CACHE_DAYS`: number of days to keep remote media cached in storage.
- `GTS_SMTP_*`: settings to allow your GoToSocial instance to connect to an email server and send notification emails.
If you decide to set/change any of these variables later on, be sure to restart your GoToSocial instance after making the changes.
!!! tip
For help translating variable names from the config.yaml file to environment variables, refer to the [configuration section](../../configuration/index.md#environment-variables).
## Start GoToSocial
With those small changes out of the way, you can now start GoToSocial with the following command:
