README.md

+# LAMBDA-RUST COQ DEVELOPMENT
+
+This is the Coq formalization of lambda-Rust.
+
+## Prerequisites
+
+This version is known to compile with:
+
+ - Coq 8.5pl2
+ - Ssreflect 1.6
+
+You will furthermore need an up-to-date version of
+[Iris](https://gitlab.mpi-sws.org/FP/iris-coq/).  Run `git submodule status` to
+see which git commit of Iris is known to work.  You can pick between using a
+system-installed Iris (from Coq's `user-contrib`) or a version of Iris locally
+compiled for lambda-Rust.
+
+## Building Instructions
+
+To use the system-installed Iris (which is the default), run `make iris-system`.
+This only works if you previously built and installed a compatible version of the
+Iris Coq formalization.  To use a local Iris (which will always be the right
+version), run `make iris-local`.  Run this command again later to update the
+local Iris, in case the preferred Iris version changed.
+
+Now run `make` to build the full development.
