# Configuration options You can either use a `config.yml` file in the root directory of vikunja or set all config option with environment variables. If you have both, the value set in the config file is used. Variables are nested in the `config.yml`, these nested variables become `VIKUNJA_FIRST_CHILD` when configuring via environment variables. So setting ```bash export VIKUNJA_FIRST_CHILD=true ``` is the same as defining it in a `config.yml` like so: ```yaml first: child: true ``` # Default configuration with explanations This is the same as the `config.yaml` file you'll find in the root of vikunja. ```yaml service: # This token is used to verify issued JWT tokens. # Default is a random token which will be generated at each startup of vikunja. # (This means all already issued tokens will be invalid once you restart vikunja) JWTSecret: "cei6gaezoosah2bao3ieZohkae5aicah" # The interface on which to run the webserver interface: ":3456" database: # Database type to use.
