I've tried to run the example under "Configuring the Parser" and get some errors. What could be my problem?

Errors

error: cannot find derive macro Parser in this scope
error: cannot find attribute command in this scope
error: cannot find attribute arg in this scope
error[E0599]: no function or associated item named parse found for struct Cli in the current scope

Cargo.toml

[package]
name = "hello_cargo"
version = "0.1.0"
edition = "2021"

[dependencies]
clap = "4.3.5"

The tutorial makes a reference to this

This requires enabling the derive feature flag.

But if you aren't as familiar with feature flags, this isn't as helpful.

More specifically on the front page we have

$ cargo add clap --features derive

Maybe we should push that down into the tutorial...
