The directory structure and templates provide the majority of the configuration for a site. In fact a config file isn't even needed for many websites since the defaults used follow commonly used patterns.

Hugo expects to find the config file in the root of the source directory and will look there first for a config.yaml file. If none is present it will then look for a config.json file, followed by a config.toml file.

Examples

The following is an example of a yaml config file with the default values:

builddrafts: false
indexes:
   category: "categories"
   tag: "tags"
baseurl: "http://yoursite.com/"
...

The following is an example of a json config file with the default values:
