 ## Installation
 
-You must have both [Arduino](https://www.arduino.cc/en/main/software) and [Teensyduino](https://www.pjrc.com/teensy/td_download.html) installed before proceeding. Double-check that your installed Teensyduino version matches the files provided in this repository. This repository is currently using version [**1.46**](https://www.pjrc.com/teensy/td_146). If you don't know your Teensyduino version, compile a blank sketch with a Teensy board selected and the Teensy Loader will open. In the Teensy Loader window select `Help -> About` and it will tell you the version number. If your version does not match you will have to reinstall or update the Teensyduino software.
