-## Formatting Responses using `--pretty` flag
-
-You can optionally return outputs of commands in  human-readable, tabular format instead of `JSON`. To enable this option, simply add the `--pretty` flag as a top level flag. For instance, you wallet's balance in a pretty format, you can run:
-
-```shell
-cargo run -- --pretty -n signet wallet -w {wallet_name} balance
-```
-This is available for wallet, key, repl and compile features. When ommitted, outputs default to `JSON`.
