# Universal DIG installer bootstrap (macOS / Linux) — the one-line install.

#
# Downloads the dig-installer binary for this OS/arch from the latest
# DIG-Network/dig-installer release, then runs it. By default the installer is a
# THIN SHIM that resolves + installs the latest digstore CLI (the $DIG content
# tooling) for this OS/arch and adds it to PATH. Pass installer flags after
# `-s --` to also install other components:
#
#   # ALSO install + start the dig-node local node as a service (+ dig.local):
#   curl -fsSL .../install.sh | sh -s -- --with-dig-node
#   # ALSO download the DIG Browser native installer:
#   curl -fsSL .../install.sh | sh -s -- --with-browser
#   # Everything, machine-readable result:
#   curl -fsSL .../install.sh | sh -s -- --with-dig-node --with-browser --json
#
# Flags are forwarded verbatim to dig-installer (see `dig-installer --help` /
# `dig-installer --help-json`).
