-### Wallet Descriptor
+### Wallet
+Here you can load view and save wallet descriptors, add or change passphrases, customize wallet's attributes,  generate and load a BIP85 child mnemonics.
+
+#### Wallet Descriptor
+
+A Bitcoin Wallet Output Descriptor defines a set of addresses in a wallet. It includes the following information:
+
+- Script Type: Specifies the type of script (e.g., P2PKH, P2SH, P2WPKH).
 
-When you select this option for the first time, you will be prompted to load a wallet. The camera will activate, and you will need to scan a wallet backup QR code generated by your wallet coordinator software. If the scan is successful, a preview of the wallet will be displayed for confirmation. If you abort the scan, you can alternatively load the wallet descriptor from an SD card.
+- Derivation Path: Defines the path used to derive keys.
+
+- Public Keys or Extended Public Keys: Includes xPub, yPub, zPub.
+
+Output descriptors standardize how wallets generate addresses, ensuring compatibility and security. They help wallets and other software understand how to derive and verify the addresses used in transactions.
+
+For multisig wallets, it is essential to load a descriptor to check addresses and perform full PSBT verification. For single-sig wallets, loading a descriptor is optional and serves as a redundancy check of the coordinator's wallet attributes.
+
+When you select the "Wallet Descriptor" option for the first time, you will be prompted to load a wallet descriptor via QR code or SD card. After loading, a preview of the wallet attributes will be displayed for confirmation.

-If you access this option again after having loaded your wallet, you will see the wallet's name, fingerprints and the abbreviated XPUBs of all cosigners, along with a QR code containing the exact data that was initially loaded. If an SD card is inserted, you can save the descriptor to it. Additionally, if you have a thermal printer attached, you can print this QR code.
+If you access the "Wallet Descriptor" option again after loading your wallet, you will see the wallet's name, fingerprints, and the abbreviated XPUBs of all cosigners, along with a QR code containing the exact data that was initially loaded. If an SD card is inserted, you can save the descriptor to it for later use without the assistance of a coordinator. Additionally, if you have a thermal printer attached, you can print this QR code.
+
+Krux also allows you to verify a descriptor's receive and change addresses without the need to load private keys. Simply turn on your Krux, access "Tools" -> "Descriptor Addresses," and load a trusted descriptor from a QR code or SD card.
+
+Please note that if you customize the wallet parameters or restart the device, the descriptor will be unloaded, and you may need to load it again to check addresses.

+
+#### BIP85
+
+Bitcoin BIP85, also known as the Deterministic Entropy From BIP32 Keychains, allows for the generation of deterministic entropy using a BIP32 master key. This entropy can then be used to create various cryptographic keys and mnemonics (e.g., BIP39 seed phrases). BIP85 ensures that all derived keys and mnemonics are deterministic and reproducible, meaning they can be recreated from the same master key. This feature is useful for securely managing multiple child keys from a single master key without the need to store each one separately.

+
+Choose between a 12 or 24 words child then type the desired index to export a child mnemonic. After being presented to the new mnemonic, you can choose to load and use it right away.
 
-Please note that once a wallet is loaded, it cannot be changed. To load a different wallet, you will need to restart the device and re-enter your mnemonic.
+Please note passphrases will be removed when loading a BIP856 child.
