Getting Setup

Once we have sent you a license key, create a new file called feyn.key or .feynkey and put that key in that file. That file should be located in your home or .config folder.

If this has worked then the next time you import feyn in a python environment you will be met with the following message:

"This Feyn package and QLattice is licensed to [your name], [your organistion]. By using this software you agree to the terms and conditions which can be found at https://abzu.ai/privacy."
