-## Features:
+## Features
+
 - C++23 implementation
+- Clang and GCC support (MSVC support planned)
 - Fully constexpr and SFINAE-friendly
-- Supports:
-  * Ranges of any iterator category including `contiguous_range<R>`
-  * `borrowed_range<R>`, `range<const R>`, `copyable<R>`, and `sized_range<R>`
+- Type-erased interfaces for
+  * all input range categories including `contiguous_range<R>`
+  * `borrowed_range<R>`, `common_range<R>`, `copyable<R>`, `range<const R>`, and `sized_range<R>`
 - No allocation performed for small view and iterator types
