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

export VIKUNJA_FIRST_CHILD=true

is the same as defining it in a config.yml like so:

first:
    child: true

Default configuration with explanations

This is the same as the config.yaml file you'll find in the root of vikunja.
