 # Data Structures
+
+UCX provides a [](linked_list.h.md) and [](array_list.h.md) implementation over a common [](list.h.md) interface,
+as well as an [](hash_map.h.md) implementation over a [](map.h.md) interface, and a basic [](tree.h.md) implementation.
+
+Additionally, UCX provides an abstraction for [iterators](iterator.h.md) that work with all collection types, and
+plain C arrays.
+
+The design goal of this API was to provide high level abstractions (functions in lowerCamelCase) and low level
+implementations (functions in snake_case).
+This way you can freely choose whether to use the predefined implementations for the various collection types,
+or to implement your own collections using the low level API.
