I ended up inspecting "curl -fsSL https://get.statusnook.com | sudo bash" and extracting the script so I could see what it did:
https://gist.github.com/simonw/09b8817b4010cf32e4bfcbe929dcd...
It downloads either the arm64 or amd64 built binaries, both of which are also available from the GitHub releases page: https://github.com/goksan/Statusnook/releases/tag/v0.0.0
Feature request: add those to the README too!
