+++ title = "User guide" description = "How to use each App on the Cardputer: the keys, what the screens show, and what is written to the SD card." template = "guide-index.html" sort_by = "weight" page_template = "guide-page.html" +++ This guide says what the firmware does **today** and nothing else. Start with the basics (the keys, the Launcher, the first start), then read the page of any App. It describes the latest release; the numbers and key names come from the firmware's own source. **The mesh messenger is planned, not built.** The LoRa Scanner listens to Meshtastic traffic and shows it, but the device sends nothing yet: that is the next milestone and waits for a second node to test with.
