 ## DISCLAIMER
 
-This firmware is **WORK IN PROGRESS and NOT READY TO USE YET**. The master branch is empty **until the first release** of the firmware with core functionality implemented. At the moment all the code is in the [0.0.0-alpha branch](https://github.com/cryptoadvance/specter-diy/tree/0.0.0-alpha).
+This firmware is **WORK IN PROGRESS — USE AT YOUR OWN RISK**, better on testnet. 
 
 This wallet is a **FUNCTIONAL PROTOTYPE**. This means we use it to experiment with user interface, communication methods and new interesting features (like anti chosen-nonce protocol, CoinJoin and Lightning). But this prototype is not ment to be secure. That's why **we don't store your private keys on the device** - you need to type your recovery phrase every time you power it on.
 
+We will add the #Reckless option later on that would allow to store recovery phrase on the device.

 ## What is this project for?
 
 It is a Do-It-Yourself airgapped hardware wallet that uses QR codes for communication with the computer (i.e. [Specter Desktop app](https://github.com/cryptoadvance/specter-desktop) on top of Bitcoin Core). It can be used as an additional item in your multisignature setup that has a completely different security model:

+# Waveshare Barcode scanner configuration
+
+By default this scanner uses USB for communication. We need to change this setting to UART.
+
+Configuration is done by scanning special QR codes. It needs to be done only once.
+
+First, power it from microUSB cable (i.e. powerbank or laptop) or from the board - connect VCC cable to 5V of the board and GND to GND.
+
+Then scan the following QR codes one by one. To scan a QR code you need to press the TRG button on the scanner - if scan was successfull you will hear the beep.
+
+![](./pictures/waveshare_config.jpg)
+
+Now the scanner is configured and we can connect it to the board. Solder a wire to a button as shown on the picture below and connect the wires.
+

+
+For convenience you can buy an Arduino Protype shield and solder & mount everything on it (i.e. [this one](https://www.digikey.com/catalog/en/partgroup/proto-shield-rev3-uno-size/79347))
