+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/atmelavr-and-arduino/ardiono-engduino-library
+
+    # Process example project
+    > platformio run
+
+    # Upload firmware
+    > platformio run --target upload
+
+    # Clean build files
+    > platformio run --target clean
