+coq-smt-check
+=============
+
+This is a simple way to invoke an SMT solver (currently Z3) on Coq goals.
+It does *NOT* generate proof objects. It is meant purely for sanity checking
+goals.
+
+The main tactic is 'z3 solve' which invokes z3 on the current goal. The
+core of the plugin is the conversion from Coq to SMT2 format. At the moment,
+the conversion handles the following:
+
+ - boolean connectives, /\, \/, not
+ - equality
+ - variables
+ - real numbers, +, -, /, constants
+
+If your problem fits in this fragment (it can contain other facts as well), then
+you can run:
+
+   z3 solve.
+
+If the tactic succees then the solver solved the tactic. If it fails it will
+display an error message. To get more information about the problem that was
+passed to the smt solver, run 'z3 solve debug'.
+
+See the test-suite directory for examples.
+
+Install from OPAM
+-----------------
+Make sure you added the [Coq repository](coq.io/opam/):
+
+    opam repo add coq-released https://coq.inria.fr/opam/released
+
+and run:
+
+    opam install coq-smt-check
+
