 ## Limitations
-- Currently Linux only (please contribute Windows support!)
-- Currently X86_64 only (please contribute ARM64 support!)
-- All of the limitations of Dynamorio apply. The program must be reasonably well behaved.
+- Currently Linux only (please contribute Windows and macOS support!)
+- Currently X86_64/ARM64 only (please contribute support for other architectures)
+- All of the limitations of Dynamorio apply. (The program must be reasonably well behaved. You should assume a sufficiently motivated program can detect whether it is running under Dynamorio.)
 - Some state may be shared with the target process; while Dynamorio
 attempts to isolate our libc (and other libraries) from the target, OS structures (e.g. fds)
 are shared.
