Click more options in the top right menu bar in the corner of your image or product.
Select Add overlay text from the dropdown menu.
Type directly into the overlay to add text.
To adjust the font, color, size etc., highlight the text to open the font settings as explained here.
There are two options for moving overlay text:
In order to move the overlay text around a single image, make sure it's not in a grid and then enable free transform.
After selecting Free transform, click Add overlay text from the more options menu.
With free transform enabled first, you will see a dotted box around the overlay text.
This means you are able to move the overlay text freely around the image.
To move the overlay text around an image in a grid, simply turn on the advanced grid to move the text within the image.
