The whole configuration part is happening in one file:
_config.yml. Inside this file, you can add and configure informations about your website.
Every part of the website is configurable here like:
- Basic information about the website (title, description, language…)
- Top navigation
- Footer content
- Pagination settings
- And much more
The list of keys to configure are in the [GitHub README file](https://github.com/bellangerq/neige-theme) so check it out. There is also a [configuration example file](https://github.com/bellangerq/neige-theme/blob/master/_config.yml) so you can see how it look.
