+//! ## Unstable Features
 //!
 //! hyper includes a set of unstable optional features that can be enabled through the use of a
 //! feature flag and a [configuration flag].
 //!
 //! The following is a list of feature flags and their corresponding `RUSTFLAG`:
+//!
 //! - `ffi`: Enables C API for hyper `hyper_unstable_ffi`.
 //! - `tracing`: Enables debug logging with `hyper_unstable_tracing`.
 //!
-//! Enabling an unstable feature is possible with the following `cargo` command, as of version `1.64.0`:
+//! For example:
+//!
 //! ```notrust
-//! RUSTFLAGS="--cfg hyper_unstable_tracing" cargo rustc --features client,http1,http2,tracing --crate-type cdylib
-//!```
+//! RUSTFLAGS="--cfg hyper_unstable_tracing" cargo build
+//! ```
