Prevent members from editing pages & lists / apps in SharePoint 2013

In SharePoint 2013, the default members group has rights to edit pages and lists / apps.  Here's how I resolved such a problem.

1. Create a copy of the "Contribute" site level permission.
   1. Name it "User"
   2. Give it the following description.  "Can view, add & update list items and documents without editing pages."
   3. Under List Permissions, uncheck "Edit Items - Edit items in lists, edit document libraries, and customize Web Part Pages in document libraries.
   4. Save it.

2. Create new group called "YourSiteName Users" and assign it the "User" site level permission and following "about me" description... "Can view, add & update list items and documents without editing pages."

3. Set the new group as the default members group for the site or site collection.
