 These two commands are functionally equivalent, they run the gate with one
 backend node, some keys and otherwise default settings:

 ### Key
 
-NeoFS (`--neofs-key`) is mandatory parameter. NeoFS key can be a path to private key file (as raw bytes), 
-a hex string or (unencrypted) WIF string.
+Wallet (`--wallet`) is mandatory parameter. It is a path to wallet file. You can provide password to decrypt wallet
+via `S3_GW_WALLET_PASSPHRASE` variable or you will be asked to enter the password interactively. 
+You also can specify account address to use from wallet using `--address` parameter.
