 ### Keys
+
 You can provide a wallet via `--wallet` or `-w` flag. You can also specify the account address using `--address`
 (if no address provided default one will be used). If wallet is used, you need to set `HTTP_GW_WALLET_PASSPHRASE` variable to decrypt the wallet.
 If no wallet provided, the gateway autogenerates a key pair it will use for FrostFS requests.

 The gateway supports downloading files by common prefix (like dir) in zip format. You can enable compression
 using config or `HTTP_GW_ZIP_COMPRESSION=true` environment variable.
 
 ### Logging

 You can specify logging level using variable:
