I am building a new site using Magento 2.1 Community and am trying to add some fairly standard pages. I have no trouble adding these pages from Content->Elements->Pages->Add New Page but when I navigate to their link there is no header and footer on the page.
Looking for a guide link to how this is typically setup, I did run through the user guide and on this page: it just has a note
"Now that your page is complete, it can be added to your store navigation, linked to other pages, or added as a link in the footer of your store. You can also use it as your new home page."
What are the typical steps I need to follow to add the site header bar to this page (or visa versa, not sure on the relationship there) and do so for all content pages I create.
I am using the default Luma theme. Various posts suggest editing a variety of xml files. Am I better served to create my own theme to preserve these changes or is there a module I should consider to make this process easier or is there a more complete guide that someone can point me to which will help answer this?
I am coming from a string familiarty with standard CMS's like Drupal and Wordpress as well as SaaS eCommerce like Shopify so aware of CMS fundamentals just not how they are handled in Magento.
