+DO NOT MODIFY THE CONTENTS OF THIS DIRECTORY
+
+Any adjustment to bundled fonts will result in an altered fingerprint. Font
+fingerprinting is more than just detecting what fonts you have, it also includes
+font fallbacks and characters (unicode code points) and any change in those can
+be measured.
+
+
+SOURCES:
+
+- Linux fonts are from TOR Browser bundle
+- Windows fonts are from Windows 11 22H2.
+- Mac OS fonts are from macOS Sonoma.
