 ## Goal: Perform test applications on various platforms and check that they run as expected
 
+
+The `./compile_and_test_for_board.py` script can be used to run all compilation
+and **automated** tests for one board, not the manual tests.
+
+### Usage
+
+Run 02 `compile_and_test_for_board.py` script with your test board connected.
+
+    ./compile_and_test_for_board.py path_to_riot_directory board_name [results]
+
+It prints the summary with results files relative to `results_dir/board` to have
+a github friendly output.
+
+Failures and all tests output are saved in files.
+They can be checked with:
+
+    find results/ -name '*.failed'
+    find results/ -name 'test.success'
+
