# QR ## `` - `value` - actions: set ```xml ``` ## Guidance - What it encodes: `value`, the text content, or a bound node's text. - A Wi-Fi network: `secret`; no `password` for an open network, `hidden="true"` on `wifi` for a hidden one. - Square: the same `width` and `height` (256 without them). At most 1,273 plain characters; longer draws nothing. - `alt` says what scanning does; put the link or the network and password in a label beside it.
