# CxLLM-PLG > CxLLM Installer plug-in Apple Installer.app plug-in (Objective-C) that drives the macOS install/upgrade flow for the CxLLM bundle. [![ci](https://git.cxllm-studio.com/CxAI-LLM/CxLLM-PLG/actions/workflows/ci.yml/badge.svg)](https://git.cxllm-studio.com/CxAI-LLM/CxLLM-PLG/actions) [![license](https://img.shields.io/badge/license-MIT-7C3AED)](LICENSE) [![category](https://img.shields.io/badge/category-installer-plugin-1F6FEB)](#) ## Overview `CxLLM-PLG` is part of the **CxLLM** product family — a layered runtime that spans Apple kernel extensions, user-space frameworks, host applications, and spatial / web surfaces. This module focuses on **installer-plugin** concerns and is intentionally narrow so that the CxLLM monorepo can compose targets without pulling in unrelated dependencies. ## Repository layout - `CxLLM-PLG/` — primary source folder (matches the Xcode group / SwiftPM root). - `CxLLM-PLG.xcodeproj` — Xcode project (where applicable). - `Makefile` — common entry points (`build`, `test`, `lint`, `clean`). - `.github/workflows/ci.yml` — CI pipeline (Xcode build + lint). - `docs/` — architecture notes and ADRs. ## Quick start ```bash # Build (defaults to Debug for the host platform): make build # Run the full test suite (unit + UI where applicable): make test # Static analysis + format check: make lint ``` ## Versioning This module follows [Semantic Versioning 2.0](https://semver.org/) and is released in lock-step with the umbrella **CxLLM** product line. See [`CHANGELOG.md`](CHANGELOG.md) for the user-facing change log. ## Security Please report security issues per [`SECURITY.md`](SECURITY.md).
