# Install (prebuilt binary or build from source)

# Or build manually:
cd zig && ./fetch-vendor.sh && zig build -Doptimize=ReleaseFast

# Claude Code — the plugin is the one-step path. It ships the skill, the hook
# and the MCP server together, and its launcher finds or fetches the binary.
claude plugin marketplace add munhq/codeindex
claude plugin install codeindex@codeindex

# Without the plugin (or for a different MCP client), register the binary
# directly. Do not do both: two registrations mean two servers, two copies of
# every tool schema, and two writers on one snapshot. install.sh detects the
# plugin and skips this step when it is present.
