This walks one complete path from an empty account to a QR code you can print and scan. It is not the only order that works — Collections, Items, Links and Pages are independent, so creating a hundred Links first and connecting them months later is equally valid. Before you start: you need a QRtub account and a team selected in the team switcher at the top of the sidebar. Parts of the app still say “tub” where these docs say “Collection” — the entity was renamed and the labels have not all caught up.

​
Create a Collection

In the sidebar, click the + next to the section labeled Tub — the old name for Collections, still on the button. The New tub screen it opens offers two cards — Connects to one destination and Connects to several — plus a row of starter templates. Picking any of them creates the Collection immediately. There is no form: the Collection gets an automatic sequential name (Tub1, Tub2, and so on) and you land on its empty grid, where the name, description and cover image are all editable in place. The two cards set what a scanned code does by default — pass through to one destination, or open a Page listing several — and that is changeable later in settings. Click Add your first item, give it a name, and save. Collections created this way default to random link generation, so QRtub mints a Link at the moment the Item is saved and confirms it with a message naming the new slug. To see it, open the Item and switch to its Access Links tab — the full URL is listed there, in the form qrtub.com/r/x5fgd. An Item can hold more than one Link. If a Collection’s link generation is set to None — the default for older Collections — saving an Item mints no Link, and you attach one yourself as below. Open Access Link in the sidebar and click Create Link. Choose a strategy — Random, Numbered, or Custom — and for Random you can create up to 100 in one request. Nothing needs to exist first: a Link with no Item and no destination is a valid, permanent, printable Link. To connect one, use the row menu on any Link and choose Assign to Item; the picker searches the whole team, so the Item can live in any Collection. An Item’s Access Links tab works from the other direction, listing the team’s unassigned Links so you can attach a pre-printed code there.

​
Download the QR code

From a Link’s row menu, choose Download QR Code. You get a single PNG at 1024 px, black on white, with a 2-module quiet zone; select several Links first and you get a zip of PNGs instead. There is no SVG export and no error-correction setting today. Open the Item and use the Destination tab to set where a scan goes, or the Page tab to build a screen with several Destinations. Either can be changed at any time without touching the printed code. A Destination can be a fixed URL or a template that inserts this Item’s own field values, so one template serves every Item in the Collection. Values are inserted exactly as stored — no URL-encoding — so a field containing a space or an & breaks the resulting link.
