 ## Introduction
 
-Project settings are always configured by using a YAML configuration file in the
-project directory named `mkdocs.yml`.
+Project settings are configured by default using a YAML configuration file in
+the project directory named `mkdocs.yml`. You can specify another path for it
+by using the `-f`/`--config-file` option (see `mkdocs build --help`).
 
 As a minimum, this configuration file must contain the `site_name` and
 `site_url` settings. All other settings are optional.
