+Note on C++ standard library support
+----------------------------------
+
+This library uses C++ timing facilities (``std::chrono``). It requires a
+toolchain and board core that provide the C++ standard library. Older or
+constrained Arduino cores (for example some AVR/Uno toolchains) may not
+provide ``<chrono>`` and will fail to compile. For these boards prefer
+PlatformIO or newer Arduino cores that include full C++ support.
+
+If you target constrained boards, see the Arduino usage documentation for
+workarounds and recommended cores.
