+Custom headers
+--------------
+
+Manta allows additional custom headers to be
+[added with an object](https://apidocs.joyent.com/manta/storage-reference.html#custom-headers).
+When the object is retrieved, the custom headers are returned as well.
+
+ruby-manta supports this, by adding any :m_* arguments as headers to an object.
+For example, to add an 'M-Foobar' header with an object:
+
+```ruby
+
+    client.put_object(/john/stor/passwd', 'weak', :m_foobar => 'baz')
+```
+
+A reminder when reading back headers (e.g. using get_object()) that header names
+are case-insensitive (see RFC 2616). 'M-Foobar' may return as 'm-foobar'.
