 //! # KIVI format deserializer
+//!
+//! KIVI is a simple text format for storing keys with associated values on separate lines.
+//! While it is not as widely known as formats like JSON or INI, it is straightforward
+//! and particularly useful in specific contexts where keys or values consist
+//! of multiple lines of text.
+//!
+//! An example of a configuration file in KIVI format:
+//!
+//! ```text
+//! host
+//! 127.0.0.1
+//!
+//! port
+//! 54321
+//!
+//! timeout
+//! 12ms
+//! ```
+//!
+//! `host`, `port` and `timeout` are keys; `127.0.0.1`, `54321`, `12ms` are values.
+//! It is quite similar to properties or INI file that store key-value pair in a single line.
+//!
+//! In KIVI format, the key and/or value may span over multiple lines:
+//!
+//! ```text
+//! host
+//! 127.0.0.1
+//!
+//! port
+//! 54321
+//!
+//! timeout
+//! 12ms
+//!
+//! "General
+//!  description"
+//! "This configuration file
+//!  should be placed in the same
+//!  directory where the servers
+//!  binary is placed"
+//! ```
+//!
