 ## Repository: A repository for all kinds of entities.
 
-`Repository` provides storage for multiple data types, it provides
-its own kind of index handle called `EntityId` and its own kind of typed
-handle called `EntityPtr<T>`. With these handles it allows the values
-resident in the same `Repository` to reference each other easily.
-
-The data behind the `EntityPtr<T>` handle can be accessed when you have
-a corresponding reference to the whole repository.
-
-The data behind the `EntityId` handle can be accessed when you know its
-type and have a corresponding reference to the whole repository.
-
-### Usage example:
-```rust
-// create a repository.
-let mut repo = Repo::new();
-
-// insert and retrieve a pointer handle.
-let a = repo.insert(42i32);
-assert_eq!(42i32, *a.get_ref(&repo).unwrap());
-
-// insert and retrieve a index handle.
-let b = repo.insert_for_id(42i32);
-
-// downcast from index handle to pointer handle.
-let b_ptr = b.cast_ptr::<i32>(&repo).unwrap();
-assert_eq!(42i32, *b_ptr.get_ref(&repo).unwrap());
-
-// downcasting fails when type is incorrect.
-let b_wrong_ptr = b.cast_ptr::<u32>(&repo);
-assert_eq!(None, b_wrong_ptr);
-```
