 KeePassDX can use the links generated by QR codes to register new OTP keys. But KeePassDX does not contain a QR code reader, other apps are dedicated to that and do the job very well.
 
 So you just have to use your favorite code reader app (ie: [QR & Barcode Scanner](https://github.com/dmitriy-ilchenko/QrAndBarcodeScanner)) and share the link to KeePassDX:
-1. Open your database in modification
-2. Scan your QR code with a compatible app
-3. Share the link to KeePassDX (ie: "share as text")
-4. KeePassDX switches to "Save" mode
-5. Select an entry (the otp field of the entry is automatically filled)
