+//! ## Sub-modules
+//!
+//! - `sig`: This sub-module contains the `Signature` and `PublicKey` structures and their associated methods.
+//! - `error`: This sub-module contains the ``CryptoError` error type used throughout the `crypto` module.
+//!
+//! For more detailed information, users should refer to the specific documentation for each sub-module.
