+## Test Layout ##
+
+There are several sub-directories within the openbmc-test-automation base which
+contain test suites, tools, templates, etc. These sub-directories are
+classified as follows:
+
+`tests/`: Contains the general test cases for OpenBMC stack functional
+          verification.
+
+`extended/`: Contains test cases for boot testing, network testing,
+             code update, RAS (Reliability, availability and serviceability)
+             testing, etc.
+
+`systest/`: Contains test cases for HTX bootme.
+
+`xcat/`: Contains test cases for XCAT automation.
+
+`tools/`: Contains various tools.
+
+`templates/`: Contains sample code examples and setup testing.
