 **cpp-sort** provides a full set of sorting-related features. Here are the main building blocks
 of the library:
-* Every sorting algorithm exists as a function object called a [sorter](https://github.com/Morwenn/cpp-sort/wiki/Sorters)
-* Sorters can be wrapped in [sorter adapters](https://github.com/Morwenn/cpp-sort/wiki/Sorter-adapters) to augment their behaviour
-* The library provides a [sorter facade](https://github.com/Morwenn/cpp-sort/wiki/Sorter-facade) to easily build sorters
-* [Fixed-size sorters](https://github.com/Morwenn/cpp-sort/wiki/Fixed-size-sorters) can be used to efficiently sort tiny fixed-size collections
-* [Measures of disorder](https://github.com/Morwenn/cpp-sort/wiki/Measures-of-disorder) can be used to evaluate the disorder in a collection
