+You can also test all supported archs and emulators with:

+....
+./test-user-mode \
+  --all-archs \
+  --all-emulators \
+;
+....
+
 This command would run the test four times, using `x86_64` and `aarch64` with both gem5 and QEMU.
 
 Without those flags, it defaults to just running the default arch and emulator once: `x86_64` and `qemu`.
 
+===== Quit on fail
+
+By default, tests stop running as soon as the first failure happens.
+
+You can prevent this with the `--no-quit-on-fail option, e.g.:
+
+....
+./test-user-mode --no-quit-on-fail
+....
+
+You can then see which tests failed on the test summary report at the end.

 ===== Test userland in full system
 
 Run all userland tests from inside full system simulation (i.e. not <<user-mode-simulation>>):
