+* **Note:** For ***Linux users only*** there exists an ``install.sh`` script in this project that can be run to quickly link the ArduinoCore-API to this module.
+If you are able to run that script successfully then you can skip the next steps.

 * To "complete" the core you need to copy or symlink the api folder from the [ArduinoCore-API](https://github.com/arduino/ArduinoCore-API.git) repo to the target's ``cores/arduino`` folder:
 ```sh

 **Known Bug(s):**

+__NOTE:__ You can skip this step as well if you ran ``install.sh``.
