 ### Bitcoin Recovery
 
-The private key that is exported by the tool must be converted to WIF format.
+The tool exports two WIFs for import into the Electrum Bitcoin wallet: one for mainnet (`bc1` address), and another for testnet (`tb1` address).
+Choose the one depending on your vault's environment.
 
-This needs Node.js to be installed.
+A WIF looks like: L1CujRNEhNfZgTS9b6e3hytTDu7gpUv1kiLx4ETEEhEc8nJcx4QA

-> wif.encode(239, sk, true)
-```
