+## Walkthrough
+
+We have a [walkthrough](walkthrough.md) of RustHornBelt's Coq mechanization.

+It explains in detail how to verify integer addition, model `Vec`, verify
+`Vec::new`, and verify `mem::swap` (featuring mutable borrows).
+It focuses on the things you need to know to extend our Coq mechanization.
