+#### Example: header Cache-Control
+
+``` yaml
+deploy:
+  type: s3-cloudfront
+  bucket: my-site-bucket
+  cf_distribution: mydistributionid
+  headers: {CacheControl: 'max-age=604800, public'}
+```
+
+This will set "Cache-Control" header in every file deployed to max-age 1 week. This solves "Leverage browser caching" on most page speed analyzers. For custom metadata use:
+
+``` yaml
+  headers: {Metadata : { x-amz-meta-mykey: "my value" }}
 ```
