 # ESP32 BLE for Arduino
 The Arduino IDE provides an excellent library package manager where versions of libraries can be downloaded and installed. This Github project provides the repository for the ESP32 BLE support for Arduino.
 
-The original source of the project, **which is not maintained anymore**, can be found here: https://github.com/nkolban/esp32-snippets
+The original source of the Bluedroid project, **which is not maintained anymore**, can be found here: https://github.com/nkolban/esp32-snippets
 
-Issues and questions should be raised here: https://github.com/espressif/arduino-esp32/issues <br> (please don't use https://github.com/nkolban/esp32-snippets/issues!)
+Some parts of the NimBLE implementation are based on the work of h2zero, which can be found here: https://github.com/h2zero/NimBLE-Arduino

 Documentation for using the library can be found here: https://github.com/nkolban/esp32-snippets/tree/master/Documentation
+
+For a more customizable and feature-rich implementation of the NimBLE stack, you can use the [NimBLE-Arduino](https://github.com/h2zero/NimBLE-Arduino) library.
