 ## Running Miri
 
 ```sh
-cargo +nightly run tests/run-pass/vecs.rs # Or whatever test you like.
+cargo +nightly run -- -Zmiri-disable-validation tests/run-pass/vecs.rs # Or whatever test you like.
 ```
 
+We have to disable validation because that can lead to errors when libstd is not
+compiled the right way.

 ## Running Miri with full libstd

+When Miri hits a call to such a function, execution terminates, and even when
