+# zip_view Support for the oneDPL Range APIs with C++20
+
+## Introduction
+`std::ranges::zip_view` is powerful utility enables developers to combine two or more ranges into a single view,
+where each element is represented as a tuple containing corresponding elements from each input range.
+
+## Motivations
+`std::ranges::zip_view` is a convenient way to combine multiple ranges into a single view, where each element of
+the resulting range is a tuple containing one element from each of the input ranges. This can be particularly
+useful for iterating over multiple collections in parallel. `std::ranges::zip_view` is introduced starting with C++23,
+but there are many users who work with C++20 standard yet. So, oneDPL introduces `oneapi::dpl::ranges::zip_view`,
+which the same API and functionality as `std::ranges::zip_view`.
+
+
+### Key Requirements
+`oneapi::dpl::ranges::zip_view` should have:
+- API compliance with `std::ranges::zip_view`
+- `oneapi::dpl::__internal::tuple` underhood, due to `std::tuple` has issues with swapability and device copyability.
+
+
+### Performance
+Combining `std::ranges::zip_view` with data pipelines and kernel fusion enables developers to write expressive,
+efficient code for processing multiple related datasets. This approach not only simplifies the logic but also
+optimizes performance, making it an essential technique in modern C++ development. Whether you're working with
+simple transformations or complex data processing workflows, zip_view can be a valuable utility.
