Hello!

I found link to this project from https://hackaday.com/2021/04/23/pi-based-spectrometer-puts-the-complexity-in-the-software/

Could you please add information about license of this repository — is it allowed to copy, change and use the code and images in any purpose?
It would be great to see any popular open source license.
