+### Reporting Bugs
+
+Please report bugs in [NTPClient_Generic Issues](https://github.com/khoih-prog/NTPClient_Generic/issues) if you find them.
+
+However, before reporting a bug please check through the following:
+
+* [Existing Open Issues](https://github.com/khoih-prog/NTPClient_Generic/issues) - someone might have already encountered this.
+
+If you don't find anything, please [open a new issue](https://github.com/khoih-prog/NTPClient_Generic/issues/new).
+
+### How to submit a bug report
+
+Please ensure to specify the following:
+
+* Arduino IDE version (e.g. 1.8.13) or Platform.io version
+* `ESP8266`, `ESP32` or board's Core Version (e.g. ESP8266 core v2.7.4, ESP32 v1.0.4, etc.)
+* Contextual information (e.g. what you were trying to achieve)
+* Simplest possible steps to reproduce
+* Anything that might be relevant in your opinion, such as:
+  * Operating system (Windows, Ubuntu, etc.) and the output of `uname -a`
+  * Network configuration
+
+
+### Example
+
+```
+Arduino IDE version: 1.8.13
+ESP8266 Core Version 2.7.4
+OS: Ubuntu 20.04 LTS
+Linux xy-Inspiron-3593 5.4.0-51-generic #56-Ubuntu SMP Mon Oct 5 14:28:49 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
+
+Context:
+I encountered an endless loop while trying to connect to Local WiFi.
+
+Steps to reproduce:
+1. ...
+2. ...
+3. ...
+4. ...
+```
+### Sending Feature Requests
+
+Feel free to post feature requests. It's helpful if you can explain exactly why the feature would be useful.
