 Derive to clone dyn structures.
 
-By default, Rust does not support cloning for trait objects due to the `Clone` trait requiring compile-time knowledge of the type's size. The `clone_dyn` crate addresses this limitation through procedural macros, allowing for cloning collections of trait objects. The crate's purpose is straightforward: it allows for easy cloning of `dyn< Trait >` with minimal effort and complexity, accomplished by applying the derive attribute to the trait.
+This crate is a facade that re-exports `clone_dyn_types` (for core traits and logic) and `clone_dyn_meta` (for procedural macros). It provides a convenient way to enable cloning for trait objects. By default, Rust does not support cloning for trait objects due to the `Clone` trait requiring compile-time knowledge of the type's size. The `clone_dyn` crate addresses this limitation through its procedural macros, allowing for cloning collections of trait objects. The crate's purpose is straightforward: it allows for easy cloning of `dyn< Trait >` with minimal effort and complexity, accomplished by applying the `#[clone_dyn]` attribute to the trait.
 
 ### Alternative
 
 There are few alternatives [dyn-clone](https://github.com/dtolnay/dyn-clone), [dyn-clonable](https://github.com/kardeiz/objekt-clonable). Unlike other options, this solution is more concise and demands less effort to use, all without compromising the quality of the outcome.
 
 ## Basic use-case
 
-Demonstrates the usage of `clone_dyn` to enable cloning for trait objects.
-
-By default, Rust does not support cloning for trait objects due to the `Clone` trait
-requiring compile-time knowledge of the type's size. The `clone_dyn` crate addresses
-this limitation through procedural macros, allowing for cloning collections of trait objects.
-
-##### Overview
-
-This example shows how to use the `clone_dyn` crate to enable cloning for trait objects,
-specifically for iterators. It defines a custom trait, `IterTrait`, that encapsulates
-an iterator with specific characteristics and demonstrates how to use `CloneDyn` to
-overcome the object safety constraints of the `Clone` trait.
-
-##### The `IterTrait` Trait
-
-The `IterTrait` trait is designed to represent iterators that yield references to items (`&'a T`).
-These iterators must also implement the `ExactSizeIterator` and `DoubleEndedIterator` traits.
-Additionally, the iterator must implement the `CloneDyn` trait, which allows cloning of trait objects.
-
-The trait is implemented for any type that meets the specified requirements.
-
-##### Cloning Trait Objects
-
-Rust's type system does not allow trait objects to implement the `Clone` trait directly due to object safety constraints.
-Specifically, the `Clone` trait requires knowledge of the concrete type at compile time, which is not available for trait objects.
-
-The `CloneDyn` trait from the `clone_dyn` crate provides a workaround for this limitation by allowing trait objects to be cloned.
-Procedural macros generates the necessary code for cloning trait objects, making it possible to clone collections of trait objects.
-
-The example demonstrates how to implement `Clone` for boxed `IterTrait` trait objects.
-
-##### `get_iter` Function
-
-The `get_iter` function returns a boxed iterator that implements the `IterTrait` trait.
-If the input is `Some`, it returns an iterator over the vector.
-If the input is `None`, it returns an empty iterator.
-
-It's not possible to use `impl Iterator` here because the code returns iterators of two different types:
-- `std::slice::Iter` when the input is `Some`.
-- `std::iter::Empty` when the input is `None`.
-
-To handle this, the function returns a trait object ( `Box< dyn IterTrait >` ).
-However, Rust's `Clone` trait cannot be implemented for trait objects due to object safety constraints.
-The `CloneDyn` trait addresses this problem by enabling cloning of trait objects.
-
-##### `use_iter` Function
-
-The `use_iter` function demonstrates the use of the `CloneDyn` trait by cloning the iterator.
-It then iterates over the cloned iterator and prints each element.
-
-##### Main Function
-
-The main function demonstrates the overall usage by creating a vector, obtaining an iterator, and using the iterator to print elements.
-
+This example demonstrates the usage of the `#[clone_dyn]` attribute macro to enable cloning for trait objects.
 
 ```rust
-# #[ cfg( not( all( feature = "enabled", feature = "derive_clone_dyn" ) ) ) ]
-# fn main() {}
-# #[ cfg( all( feature = "enabled", feature = "derive_clone_dyn" ) ) ]
-# fn main()
-# {
-
-  use clone_dyn::{ clone_dyn, CloneDyn };
-
-  /// Trait that encapsulates an iterator with specific characteristics, tailored for your needs.
-  // Uncomment to see what macro expand into
-  // #[ clone_dyn( debug ) ]
-  #[ clone_dyn ]
-  pub trait IterTrait< 'a, T >
-  where
-    T : 'a,
-    Self : Iterator< Item = T > + ExactSizeIterator< Item = T > + DoubleEndedIterator,
-    // Self : CloneDyn,
-    // There’s no need to explicitly define this bound because the macro will handle it for you.
-  {
-  }
