Now that you have been accustomed with collections (if not, you can read more here), you are one step away from creating a PDF booklet to print-at-home.
You can start the clicking the "Create a booklet" button on your collection.
Your configuration modal will appear. Make sure you select the "Print-at-home (PDF)" option as shown below and start configuring you booklet. You can select between Cover and Interior options and preview each output by clicking the "Build it!" button.
After previewing your selections, you can either download the booklet as PDF, or click the "configure" button and change your selection to see different versions.
That's it 🎊
