+
+    To run a specific test, use `make build generate-accounts test/<TEST NAME>`, where `<TEST NAME>` is the file name of the test (_for more precision use a relative path: `test/test/<PATH>`_) excluding the `.bats` suffix.
+
+    To run only the tests in `template.bats`, use `make test/template` (or `make test/parallel/set2/template`).
