Hello
When installed it creates a menu on the top admin bar labeled “Simply Symphony” Select a new post or new page, this will load the editor.
When the editor loads on the top toolbar are icons for inserting objects into your page, Text Boxes, Images, Embeds. You should start with a text box.
The top toolbar has a help icon with videos to show the basics.
Please make sure you have the update we released today, it has links to our new forums in the help menu, and a few pre-built objects that may speed along your page building.
Thank You
Simply Symphony
