 # Arduino_GigaDisplay
 
-Minimal library for controlling the built-in RGB on the GIGA Display Shield via the IS31FL3197 driver (I2C).
+This library contains a set of examples to use the [GIGA Display Shield](docs.arduino.cc/hardware/giga-display-shield). Upon installing this library from the Arduino IDE, the following libraries will also be installed:
+- [ArduinoGraphics](https://github.com/arduino-libraries/ArduinoGraphics)
+- [Arduino_GigaDisplayTouch](https://github.com/arduino-libraries/Arduino_GigaDisplayTouch)
+- [Arduino_BMI270_BMM150](https://github.com/arduino-libraries/Arduino_BMI270_BMM150)
+
+It will also install the [lvgl](https://github.com/lvgl/lvgl) library, which is required for a large number of examples in this repository.
+
+>For any issues with the examples, please visit the repository of the library in the links above.
