# Puts the board in ~/.local/share/agent-board and an `agent-board` command in ~/.local/bin.
# Needs python3 (3.10+) and git or curl. No sudo, nothing installed system-wide, no packages from PyPI.
# Run it again at any time to update.
#
# Options (when piping:  curl ... | sh -s -- --with-limits-mod):
#   --with-limits-mod   also install the companion Claude Code mod that feeds your rate limits to the board
#   --uninstall         remove the board (your settings in ~/.config/agent-board are kept)
#   --help              this text
