+examples/default
+================
+This application is a showcase for RIOT's hardware support. Using it
+for your board, you should be able to interactively use any hardware
+that is supported.
+
+To do this, the application uses the `shell` and `shell_commands`
+modules and all the driver modules each board supports.
+
+`shell` is a very simple interactive command interpreter that can be
+used to call functions.  Many of RIOT's modules define some generic
+shell commands. These are included via the `shell_commands` module.
+
+Additionally, the `ps` module which provides the `ps` shell command is
+included.
+
+Usage
+=====
+
+Build, flash and start the application:
+```
+export BOARD=your_board
+make
+make flash
+make term
+```
+
+The `term` make target starts a terminal emulator for your board. It
+connects to a default port so you can interact with the shell, usually
+that is `/dev/ttyUSB0`. If your port is named differently, the
+`PORT=/dev/yourport` variable can be used to override this.
+
+
+Example output
+==============
+
+The shell commands come with online help. Call `help` to see which commands
+exist and what they do.
+
+Running the `help` command on an iotlab-m3:
+```

+
+RIOT specific
+=============
+
+The `ps` command is used to analyze the thread's state and memory
+status.
+
+
+Networking
+==========
+
+The `ifconfig` command will help you to configure all available network
+interfaces. On an iolab-m3 it will print something like:
+```
+2015-09-16 16:58:37,762 - INFO # ifconfig
+2015-09-16 16:58:37,766 - INFO # Iface  4   HWaddr: 9e:72  Channel: 26  NID: 0x23  TX-Power: 0dBm  State: IDLE CSMA Retries: 4

+2015-09-16 16:58:37,770 - INFO #            Source address length: 2
+```
+
+Type `ifconfig help` to get an online help for all available options (e.g.
+setting the radio channel via `ifconfig 4 set chan 12`).
+
+The `txtsnd` command allows you to send a simple string directly over the link
+layer using unicast or broadcast. The application will also automatically print
+information about any received packet over the serial. This will look like:
+```
+2015-09-16 16:59:29,187 - INFO # PKTDUMP: data received:
