 ### Keys
-
+You can provide wallet via `--wallet` or `-w` flag also you can specify account address using `--address` 
-By default gateway autogenerates key pair it will use for NeoFS requests. If
+(if no address provided default one will be used). If wallet is used you need to set `HTTP_GW_WALLET_PASSPHRASE` variable to decrypt wallet. 
-for some reason you need to have static keys you can pass them via `--key` 
+If no wallet provided gateway autogenerates key pair it will use for NeoFS requests.
