Thanks @pete-may!
It's really exciting to hear from folks that are enjoying yabai + hammerspoon + stackline :-)

And thanks a ton for noticing the error in the readme & fixing it! It's more difficult than expected to ensure that documentation is up-to-date everywhere. I'm sorry for the time you lost initially diagnosing / troubleshooting this :(

I added you to the contributors list in the readme ;-)
