# JAR Contributor Workspace Setup
# Run this to set up a complete JAR contribution workspace.
# Requires: gh (GitHub CLI, authenticated), zo.space routes
#
# Usage: bash Skills/jar-contributor/scripts/setup.sh [github-username]
#
# What it does:
# 1. Forks jarchain/jar to your GitHub account
# 2. Creates persistent state directory
# 3. Prints instructions for setting up zo.space routes (must be done via Zo)
