 This Jai Module provies a means of writing tests and building a test executable
 that can be used in applications such as CI runners.
 
+## Test Executable Reference
+Test executables can be run individually or via `run_all_tests.sh` which is output in the same directory.
+Both tests and `run_all_tests.sh` have the same options:
+
+`-colors`: output colored information for easier readability
+`-verbose`: by default the output will only show test suites run, and full information on errors. Enabling verbose output indicates all tests that are run as well.
+
+## Test Harness Reference
+
+`Init_Test_Harness(suite_name: string)`: Call at the beginning of your test suite function to initialize the test suite.
+`Run_Test_Harness()`: Call at the end of your test suite function to execute all tests
+`Before_Each(#type () -> ())`: Define a function that will be run before each test
+`After_Each(#type () -> ())`: Define a funciton that will be run after each test
+`Test(test_name: string, test_proc: #type () -> ())`: Define a single test function
+
+`expect(received, expected)`: Checks for equality between the two values. Equivalent to `if (received != expected) report_test_failure()`
+`expect_true(value)`
+`expect_false(value)`
+
