-Description: Provides a header only, C++ interface to R's C
-    interface.  Compared to other approaches 'cpp4r' strives to be safe
-    against long jumps from the C API as well as C++ exceptions, conform
-    to normal R function semantics and supports interaction with 'ALTREP'
-    vectors.
+Description: Provides a header only, C++ interface to R's C API with enhancements over 'cpp11'. Enforces copy-on-write
+    semantics consistent with R's behavior. Offers improved safety when interfacing with R's C API, native support for
+    ALTREP objects, UTF-8 string handling throughout, modern C++11 features and idioms, and faster compilation with
+    reduced memory requirements. Avoids Application Binary Interface (ABI) compatibility issues by being header-only and
+    allows for headers vendoring, making it useful for restricted environments. Compared to 'cpp11', it provides support
+    for converting C++ maps to R lists, Roxygen documentation directly in C++ code, proper handling of matrix
+    attributes, support for nullable external pointers, bidirectional copy of complex number types, flexibility in type
+    conversions, use of nullable pointers, and various performance optimizations.
