# Worker CLI Nix Package
#
# This package installs the worker CLI binary from a release tarball.
# See docs/releasing-worker.md for how to create releases.
#
# To use:
# 1. Copy this to dotfiles/pkgs/worker/default.nix
# 2. Update the URL to point to your release location
# 3. Update the sha256 hash (use nix-prefetch-url --unpack <url>)
# 4. Add to your system/home configuration
