# 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.yml.sample` 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)

  # The URL of the frontend, used to send password reset emails.
  frontendurl: ""
  # The base path on the file system where the binary and assets are.
