 For that sort of thing, you're going to want to look at the configuration guide.
 This should be enough to get you going, though.
 
+### Running Test Functions
+When writing your own `main()` functions, for a test-runner. There are two ways
+to execute the test. 
+
+The classic variant
+``` c
+RUN_TEST(func, linenum)
+```
+or its simpler replacement that starts at the beginning of the function.
+``` c
+RUN_TEST(func)
+```
+These macros perform the necessary setup before the test is called and
+handles cleanup and result tabulation afterwards.
+
+### Ignoring Test Functions
+There are times when a test is incomplete or not valid for some reason. 
+At these times, TEST_IGNORE can be called. Control will immediately be 
+returned to the caller of the test, and no failures will be returned.
+This is useful when your test runners are automatically generated.
+
+``` c
+TEST_IGNORE()
+```
+
+Ignore this test and return immediately
+
+``` c
+TEST_IGNORE_MESSAGE (message)
+```
+
+Ignore this test and return immediately. Output a message stating why the test was ignored.
+
+### Aborting Tests
+There are times when a test will contain an infinite loop on error conditions, or there may be reason to escape from the test early without executing the rest of the test.  A pair of macros support this functionality in Unity.  The first `TEST_PROTECT` sets up the feature, and handles emergency abort cases. `TEST_ABORT` can then be used at any time within the tests to return to the last `TEST_PROTECT` call.
+
+    TEST_PROTECT()
+
+Setup and Catch macro
+
+    TEST_ABORT()
+
+Abort Test macro
+
+Example:
+
+    main()
+    {
+        if (TEST_PROTECT())
+        {
+            MyTest();
+        }
+    }
+
+If MyTest calls `TEST_ABORT`, program control will immediately return to `TEST_PROTECT` with a return value of zero.
