+How to buid PlatformIO based project
+====================================
+
+1. `Install PlatformIO <http://docs.platformio.org/en/latest/installation.html>`_
+2. Download `source code with examples <https://github.com/ivankravets/platformio/archive/develop.zip>`_
+3. Extract ZIP archive
+4. Run these commands:
+
+.. code-block:: bash
+
+    # Change directory to example
+    > cd platformio-develop/examples/teensy/teensy-internal-libs
+
+    # Process example project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Clean build files

+ Chat  Server
+ 
+ A simple server that distributes any incoming messages to all

+ You can see the client's input in the serial monitor as well.
+ Using an Arduino Wiznet Ethernet shield. 
+ 
+ Circuit:
+ * Ethernet shield attached to pins 10, 11, 12, 13
+ * Analog inputs attached to pins A0 through A5 (optional)
