+# MicroPython SSD1306 display via I2C protocol example
+#
+# This example demonstrates how to configure SSD1306 OLED display
+# via I2C protocol.
+#
+#
+# To run this example:
+# 1. Connect your SSD1306 display with the microcontroller.
+#    (In this example an ESP32 is used with pins: SCL = Pin 22, SDA = Pin 21.
+#    Note that IC pin numbering may not map with the board's pin numbers.
+#    Please refer the boards datasheet.)
+#
+# 2. Make sure `ssd1306` is installed via: mpremote mip install ssd1306
+#    (Alternatively, you can copy ssd1306.py to your board.)
+#
+# 3. Run the example via: mpremote run example_ssd1306_i2c.py
+#    (You can also copy this file to the board and run it.)
+#
+# 4. Observe the output on your SSD1306 OLED display.
