 5. If you test your client against our fork of jCardSim instead of a real card, keep in mind that it supports unassisted 
    key derivation, but you shouldn't use it because, as explained above, it wouldn't work on the card.
 6. If using jCardSim, only use our fork, since some of the needed algorithms are unsupported in the upstream version.
+7. The pairing code is a randomly generated password (using whatever password generation algorithm is desired). This
+password must be converted to a 256-bit key using PBKDF2 with the salt "Status Hardware Wallet Lite" and 50000 iterations.

+## Alternative installation method
+This method does not require the JavaCard SDK but requires an already compiled CAP file. The cards generated this way
+have a random PUK and pairing code so they have better security. However applet installation/removal is not disabled,
+because the script is still meant to be used during the development phase.
+
+1. Install GPShell and Python 3
+2. Put the wallet.cap file in the same directory as status_hw_perso.py
+3. Disconnect all card reader terminals from the system, except the one with the card where you want to install the applet
+4. Run the status_hw_perso.py script with no arguments.
+5. Take note of the pairing code and PUK output by the script
+
 ## Implementation notes
 
 * The applet requires JavaCard 3.0.4 or later.
