 ## Architecture
 
+**Header-Only Library**: This is a pure header-only library - all implementation is in `include/skyr/`. No compilation required!
+
 **C++23-Only Implementation**: As of the latest reboot, this library is C++23-only. Previous v1 (C++17) and v2 (C++20) versions have been removed to focus on modern C++ features.

 - `std::ranges` for range-based algorithms and views (replaces `range-v3`)
 - `uni-algo` library for Unicode processing
 
-**Key Advantage**: Minimal external dependencies - only requires `uni-algo` for Unicode support. Everything else (expected, format, ranges) is in the C++23 standard library!

+**Directory Layout**:
+- `include/skyr/` - All header files (the actual implementation)
+- `cmake/targets/` - CMake target definitions (no source code, just build configuration)
+- `tests/` - Comprehensive test suite

 ### Core Components
 
 All components are in the `skyr` namespace under `include/skyr/`:
