+#### `templatesPath`
+
+A mandatory field with the path pointing to the location where template files live (nested folders are also supported). All files without the `.mustache` extension will be ignored.
 
 _Example:_
 
 ```js
+const { join } = require( 'path' );
+
 module.exports = {
-	templatesPath: __dirname,
+	templatesPath: join( __dirname, 'templates' ),
 };
 ```
 
-It is also possible to override the default template configuration using the `defaultValues` field.

+const { join } = require( 'path' );
+
+module.exports = {
+	assetsPath: join( __dirname, 'assets' ),
+};
+```
