  - There is a `CMakeLists.txt` that's mainly there for CLion support; we don't use cmake to build any of this.
- - You can use vagrant to bootstrap a VM to test under Linux while on Darwin; this is useful when testing `seccomp`.
+ - You can use UTM to bootstrap an x86_64 VM to test with Linux while on MacOS; this is useful when testing `seccomp`.
+   Ubuntu 24.04 Server for AMD64 is the recommended Linux image to use.  Note that the
+   `script_runner_test.defaults_to_counting_all_instructions` and
+   `script_runner_test.can_bypass_deserialization_instructions` tests will fail with `execution_time_us` being greater
+   than `0` due to execution time taking longer because the tests are being run in an emulated environment. As long as
+   all tests pass in CI, it's fine if they fail in UTM when running on emulated hardware.
