  * @ingroup        Persistence client library test
  * @author         Ingo Huerner
  * @brief          Persistence Power Fail Safe Test
+ *                 For this test a computer controlled lab power supply will be used.
+ *                 The persistence_pfs_test application sends a command to the power supply
+ *                 using the serial console to switch power off for a couple of seconds to
+ *                 reboot of the system and simulate unexpected power cut in order to proof
+ *                 power fail save of persistence.
+ *
+ * @attention      To run the test the following things need to do to setup the target:
+ *                 There is a script to start this test binary.
+ *                 In otder to start this script on startup, copy the systemd service file "persistenc-pfs-test-start.service"
+ *                 to /lib/systemd/system/.
+ *                 Create also a link from /lib/systemd/system/multi-user.target.wants
+ *                 to the persistence-pfs-test-start.service in /lib/systemd/system/
