 ## Usage
 
-Note: Node.js v17.15.0 or higher is required as it [introduces support for fetch API](https://nodejs.org/tr/blog/release/v17.5.0/).

+- Node.js v17.15.0 or higher is required as it [introduces support for fetch API](https://nodejs.org/tr/blog/release/v17.5.0/).
+- When using with Ledger, please enable [blind signing](https://www.ledger.com/academy/enable-blind-signing-why-when-and-how-to-stay-safe) in the Solana app settings. TLDR: When you enable blind signing, you enable your device to approve a smart contract transaction, even though it hasn’t been able to display full contract data to you. In other words, you’re agreeing to trust, instead of verify, the transaction. You still have to manually approve each transactions.

 ### Create a multisig transaction
 
 ```
-npm start -- create -c <CLUSTER> -v <VAULT_ADDRESS> -w <WALLET_SECRET_KEY_FILEPATH> -p <PAYLOAD>
+npm start -- create -c <CLUSTER> -v <VAULT_ADDRESS> -l -lda <LEDGER_DERIVATION_ACCOUNT> -ldc <LEDGER_DERIVATION_CHANGE> -w <WALLET_SECRET_KEY_FILEPATH> -p <PAYLOAD>
 ```
 
-Example:
+To use ledger with default derivation account and change:
+
+```
+npm start -- create -c devnet -v HezRVdwZmKpdKbksxFytKnHTQVztiTmL3GHdNadMFYui -l -p hello
+```
+
+To use ledger with custom derivation account and/or change:
+
+```
+npm start -- create -c devnet -v HezRVdwZmKpdKbksxFytKnHTQVztiTmL3GHdNadMFYui -l -lda 0 -p hello
+
+npm start -- create -c devnet -v HezRVdwZmKpdKbksxFytKnHTQVztiTmL3GHdNadMFYui -l -lda 0 -ldc 1 -p hello
+```
+
+To use hot wallet :
 
 ```
 npm start -- create -c devnet -v HezRVdwZmKpdKbksxFytKnHTQVztiTmL3GHdNadMFYui -w keys/key.json -p hello
 ```
 
+---
+
 ### Execute a multisig transaction
 
 ```
 npm start -- execute -c <CLUSTER> -v <VAULT_ADDRESS> -w <WALLET_SECRET_KEY_FILEPATH> -m <MESSAGE_SECRET_KEY_FILEPATH> -t <TX_ID> -u <RPC_URL>
 ```
 
+To use ledger with default derivation account and change:
+
+```
+npm start -- execute -c devnet -v HezRVdwZmKpdKbksxFytKnHTQVztiTmL3GHdNadMFYui -l -m keys/message.json -t GSC8r7Qsi9pc698fckaQgzHufG6LqVq3vZijyu5KsXLh -u https://wormhole-v2-testnet-api.certus.one/
