How to add or edit a page
Login to the CMS > Hover over the "Home" node > Click the "..." icon
From the slide-out panel select the 'Page'.
Give your new page a name. In the bottom right part of the screen hit "Save and Publish" to finalise the creation of your page.
Your new page is now visible in the content tree.
How to re-order your pages :-) woohoo!
Steps 6 - 7
Hover over any page node with sub-pages > Right-click on the "..." icon > Select "Sort" from the slide-out panel.
You will now see a full list of the nodes below that page node > Select the page you wish to re-order and then drag it to your intended position.
Once your pages are in the correct order hit "Save" in the bottom right of the slide-out panel.
