Create a New Article (Public or Private)
The Public Article page type should be used for content that does not fit into the core navigation of a site, such as announcements or articles.
The Private Article page type is the same as a public article, except that it is private and only visible to users who are logged in.
Create a new article:
From the Site Dashboard, click on "Public Article" (or Private Article) under Create new content.
Give the page a title.
In "URL alias" put the URL you would like to have for this page. Note that if there are spaces, use a dash (-) between them (i.e. about-center).
Put your content here.
If there is an image accompanying your article/announcement, upload it here.
URL Path Settings
Make sure "generate automatic URL alias" is checked.
Keep as draft if not ready, or switch to publish to make the page live.
