 ZeroLinux ships four production-ready plugins. Enable what you need, ignore the rest.

+## ✅ Production Ready
+
+ZeroLinux is not an experiment. It is tested, versioned, and CI-verified on every commit.
+
+- **CI passes on every push** — ShellCheck static analysis on all shell files
+- **Automated plugin validation** — contract compliance checked automatically
+- **Semantic versioning** — every release follows semver strictly
+- **Safe by default** — installer never overwrites your config, always generates `restore.sh`
+- **Fully reversible** — one command uninstall, zero traces left behind
+

+
 ## Contributing
 
+**Want to add a plugin?** The plugin system is designed for exactly this. Copy the `example` plugin, follow the contract, and open a PR — CI will validate everything automatically.
+
 See [CONTRIBUTING.md](./CONTRIBUTING.md). The short version:
 
 1. Fork → branch → change → test (`make test`) → PR
 2. All PRs run CI automatically
 3. New plugins must follow the contract in `plugins/example/`
 
+**Plugin ideas welcome:** kubernetes, tmux, python/virtualenv, rust/cargo, ssh manager, and more.
