+//! # Extended Key Derivation
+//!
+//! Oftentimes, a client will want to create multiple keys. Some examples may include deriving
+//! non-hardened public keys to see how many wallets have been used, deriving multiple OpenPGP
+//! keys, or generally avoiding key reuse. While Keyforkd locks the root mnemonic and the
+//! first-level derivation, any second-level derivations acquired from Keyforkd (for example,
+//! `"m/44'/0'"`) can be used to derive further keys by converting the key to an Extended Public
+//! Key or Extended Private Key and calling [`ExtendedPublicKey::derive_child`] or
+//! [`ExtendedPrivateKey::derive_child`].
+//!
+//! # Examples
+//!  ```rust
+//! use std::str::FromStr;
+//! use keyfork_mnemonic_util::Mnemonic;
+//! use keyfork_derive_util::{*, request::*};
+//! use k256::SecretKey;
+//!
+//! # fn check_wallet<T: PublicKey>(_: ExtendedPublicKey<T>) -> Result<(), Box<dyn std::error::Error>> { Ok(()) }
+//! fn main() -> Result<(), Box<dyn std::error::Error>> {
+//! #   let mnemonic = Mnemonic::from_str(
+//! #       "enter settle kiwi high shift absorb protect sword talent museum lazy okay"
+//! #   )?;
+//!     let path = DerivationPath::from_str("m/44'/0'/0'/0")?;
+//!     let request = DerivationRequest::new(
+//!         DerivationAlgorithm::Secp256k1, // The algorithm of k256::SecretKey
+//!         &path,
+//!     );
+//!
+//!     let response = // perform a Keyforkd Client request...
+//! #       request.derive_with_mnemonic(&mnemonic)?;
+//!     let key: ExtendedPrivateKey<SecretKey> = response.try_into()?;
+//!     let pubkey = key.extended_public_key();
+//!     drop(key);
+//!
+//!     for account in (0..20).map(|i| DerivationIndex::new(i, false).unwrap()) {
+//!         let derived_key = pubkey.derive_child(&account)?;
+//!         check_wallet(derived_key);
+//!     }
+//!
+//!     Ok(())
+//! }
