Glad you’re interested in adding items!
First click Customize on the left sidebar menu

To add an item, you’ll have to select a room, then enter the item name, and other details. Note: you can only set an image from the available options. Sadly you cannot upload your own images.
If you don’t find the appropriate images, fret not, choose a lookalike image, and be sure to mention the exact measurements. Even if the image is not appropriate, you’ll the see the item name in the preview
Once done, click submit
To add a new room, click + Add Room
Enter the room details and click Submit
After you’ve added one item in the newly created room, you can add multiple items by clicking add item button
