+                the theme you’re currently editing. Switching themes will revert all the changes you’ve made in this
+                session. Themes can also be renamed by choosing them from the dropdown menu, changing the name option, and
+                saving the theme. Finally, if you’re absolutely sure, you can delete a theme by clicking the
+                <i class="fa fa-trash-o"></i> button. This action is irreversible and the theme will be gone forever.</p>
