-# Arduino Adafruit SSD1306 C/C++ example
+# Fastclock for model railroads
 
-This example shows how to use Adafruit SSD1306 on Mongoose OS in C/C++.
+Based on nRF24 module, this is a fastclock solution for operating model railroads e.g. like within FREMO association.
+
+This is the master (controller) implementation. It uses an ESP8266 based board with a 0,91" OLED display (SD1306 based) as controller and a nRF24-L01 module to send the fastclock information to the clients. Controlling happens through WLAN based web page served by this module.
