+Unionmount Testsuite
+====================
+
+xfstests can be used as a test harness to run unionmount testsuite test cases
+and provide extended test coverage for overlayfs.
+
+To enable running unionmount testsuite, clone the git repository from:
+  https://github.com/amir73il/unionmount-testsuite.git
+under the xfstests src directory, or set the environment variable
+UNIONMOUNT_TESTSUITE to the local path where the repository was cloned.
+
+Run './check -overlay -g overlay/union' to execute all the unionmount testsuite
+test cases.
