+# Periph Timer Test
+
+## About
+
+This application will test all configured peripheral timers of the target
+platform. For each timer, it will set each channel with an incrementing
+timeout: CH0 is set to 5ms, CH1 to 10ms, CH2 to 15ms and so on.
+
+## Expected Result
+
+The output should show that every channel fired after an evenly distributed
+amount of time, i.e. the diff values should be equal (with some jitter...).
+
+## Note
+
+This test does however **NOT** show whether the timeouts and diffs were correct
+in relation to the expected real-time; use e.g. tests/xtimer_msg for this.
