+## Using NotoColorEmoji
+
+NotoColorEmoji uses the CBDT/CBLC color font format, which is supported by Android
+and ChromeOS, but neither Windows nor MacOS.  No Browser on MacOS supports it, but
+Edge on Window 10 with Anniversary Update does.  Chrome on Linux will support it 
+with some fontconfig tweaking, see [issue #36](https://github.com/googlei18n/noto-emoji/issues/36).
+Currently we do not build other color font formats.
