So far, it has been tested with a Yubikey NEO on a MacBook Pro running macOS Catalina. I have no other devices to test with, but bug reports and patches may still be reviewed.
Currently this package depends on a fork of [yawn/ykoath](https://github.com/yawn/ykoath). To allow this to be built directly from this repo, the fork is added as a git submodule. This can be cloned using `git clone --recurse-submodules` or cloning normally and then executing `git submodule update --init`. Once the change has been merged upstream, the submodule and this notice will go away.
This uses [deanishe/awgo](https://github.com/deanishe/awgo) to interface with Alfred and [yawn/ykoath](https://github.com/yawn/ykoath) for interracting with the Yubikey
