nice service! windows? i know.. but you cant get a used macbook for 50$. kr install didnt work by the way but the debian linux bash cmds worked in the win10 linux subsystem.
Windows support is slated for the first half of this year (you can follow this issue: https://github.com/kryptco/kr/issues/87 ). In what environment did the kr install fail? We only currently support Bash on Ubuntu(16+) on Windows.
