+This directory house the Mercury LOOPP
+
+# Running Integration Tests Locally
+
+Running the tests is as simple as
+- building this binary
+- setting the CL_MERCURY_CMD env var to the *fully resolved* binary path
+- running the test(s)
+
+
+The interesting tests are `TestIntegration_MercuryV*` in ` github.com/smartcontractkit/chainlink/v2/core/services/ocr2/plugins/mercury`
+
+In detail:
+```
+sh
+
+make install-mercury-loop # builds `mercury` binary in this dir
+CL_MERCURY_CMD=<YOUR_REPO_ROOT_DIR>/plugins/cmd/mercury/mercury go test -v -timeout 120s -run ^TestIntegration_MercuryV github.com/smartcontractkit/chainlink/v2/core/services/ocr2/plugins/mercury 2>&1 | tee /tmp/mercury_loop.log
