 This library includes modules for defining claims, handling errors, and creating/verifying PASETO tokens.
 It leverages the `rusty_paseto` crate and currently supports PASETO Tokens V4.public.
 
-# Modules
-
-- `claims`: Defines the structure and behavior of the claims that can be embedded in a PASETO token.
-- `errors`: Provides error types and handling mechanisms for the library.
-- `maker`: Contains the logic for creating and verifying PASETO tokens.
-
-# Re-exports
-
-- `Claims`: The struct representing the claims in a PASETO token.
-- `Maker`: The struct used for creating and verifying PASETO tokens.
-
 # Usage Example
 
 ```rust
 use paseto_maker::{Maker, Claims, version::V4, purpose::Public};
 
 fn main() -> Result<(), Box<dyn std::error::Error>> {
-    let maker = Maker::new_with_keypair().unwrap();
+    let (priv_key, _public_key) = Maker::new_keypair();
+    let maker = Maker::new(&priv_key).expect("failed to create maker");
     let claims = Claims::new().with_subject("example");
     let token = maker.create_token(&claims).unwrap();
     println!("Token: {}", token);

-The `claims` module defines the structure and behavior of the claims that can be embedded in a PASETO token.
-The `errors` module provides error types and handling mechanisms for the library.
-The `maker` module contains the logic for creating and verifying PASETO tokens.
-
-The `Claims` struct and `Maker` struct are re-exported for ease of use.
