+# SETTE tests
+
+The SETTE tests are a group of validation tests made on a regular basis onto NEMO to make sure that a bug-fix or development branch won't break the model.
+It enables to test that different configuration of the code will compile, run, are restartable and reproducible. It also enable to compare the code performances to a previously-tested-reference version of the code.
+
+NEMO now uses SETTE on a regular basis using the git "continuous-integration".
+
+We will continue to do it by hand with MEDUSA, at least for now, but of course, we want to benefit from all these tests to check MEDUSA the same way!
