1. Get credits. A new workspace starts with no credits. Open Billing and credits from the account menu (or Buy credits in the sidebar) and choose a plan. See "What are credits?"
2. Try a template. Open Templates, pick a look such as Jewelry 4-Angle Collage or Clean Studio Packshot, add photos of one product and click Generate.
3. Add your products. Open Products and click Import to bring in a zip or folder (one folder per SKU), or New product for one at a time. Set a type on each product.
4. Run a small test batch. Click New batch, pick 3 to 5 products, tick Test run, and start. Review the collages.
5. Run your catalogue. When you like the look, run the full group. Then check the Listing board and Export.
Tip: the How this works guide on the Products, Batches and Listing board pages walks you through each step.
