Contact Page
You can easily create a contact page by creating a static content page and insert a jetpack Contact Form. Before doing this, make sure you have installed and activated the jetpack plugin and you have activated the Contact Form module.
Archives page
Mono includes an Archives page template, similar to this: http://demo.codestag.com/mono/archives/
In order to create such a page, create a new static page, give it a name (eg Archives) and from the Page Attributes panel on the right please select the “Archives” template. Hit save and you should be good to go.
