Install GreenBits App

Note : The dongle cannot be initialized on Android. That first step requires PC, Mac or Linux. That means you cannot start to use Citadelle directly on Android. You need a computer to initialize it once.

Initialization

Now you have to perform the first initialization of the dongle and create your wallet.

Note : Please consider to be on a safe environment computer when performing this first initialization step.

Launch the App Goochain Citadelle wallet

Plug your Citadelle in a USB port

Wait some seconds for the appearance of "Citadelle Login" button (don't click on it)

Click on "Create new Wallet" on top right.

Encrypt you mnemonics words with a password if you desire. Doing so, make sure to also copy the initial passphrase words before encryption. Encryption will allow you to store with reduced security the passphrase backup and eventually save it in heavily backed up cloud systems.
Copy the 24 words passphrase on a paper. Please really secure this paper, anyway a stealer would face the second factor challenge to move your fund. Still, this paper is an actual backup of your dongle private key. Because of the high security standard of Citadelle, it is absolutely impossible to recover the private key from the dongle after initialization. In case you lose your dongle, this paper make possible to recover your fund. So make sure the paper copy is reliable and secured. We suggest to make one new copy of this paper and to put in a really different place. For example one at your home and the other at your office desk.
When you are sure about your paper copy of the mnemonic words, tick to you confirm you have really copy on a paper the words.

Click on "Write to Citadelle", then "Save to Citadelle"

Choose a PIN code. This can be from 4 to 8 digits long.

In case you forget it, you will need to recover the wallet from the paper backup.

After 3 wrong guesses, your dongle will be wipe out. That also requires a recovery process.

Back to the initialisation page, click on "Continue" to proceed to second factor authentication enabling.

Just click on "Take me to my wallet" and you're done!

Ultimately, you have to verify your paper backup. Click on "Please verify" and enter the asked words from your unencrypted word list.

The initialization is now finished. You can Logout and proceed to the next step, where it explains how to open your wallet with your Citadelle.
