@@ -13,6 +13,22 @@ To set up audio recording + playback on the ESP32 (M5 Atom), do the following:
 
 Finally, to flash the .ino to the board, connect the board to the USB port, select the port from the dropdown on the IDE, then select the M5Atom board (or M5Stack-ATOM if you have that). Click on upload to flash the board.
 
+### Alternative - PlatformIO
+
+You don't need anything, PlatformIO will install everything for you, dependencies, tool chains, etc.
+
+Please install first [PlatformIO](http://platformio.org/) open source ecosystem for IoT development compatible with **Arduino** IDE and its command line tools (Windows, MacOs and Linux), and then enter to the firmware directory:
+
+```bash
+cd software/source/clients/esp32/src/client/
+``` 
+
+And build and upload the firmware with a simple command:
+
+```bash
+pio run --target upload
+``` 
+
 ## Wifi
 
 The board needs to connect to WiFi. Once you flash, connect to the ESP32 WiFi portal "01-Light" which will get WiFi details. Once it connects, it will ask you to enter 01OS server address. Once its able to connect, you can use the device.
