To install `sk-tracer` in your prod cluster: `kubectl apply -k k8s/kustomize/prod`\n2. To install `sk-ctrl` in your simulation cluster: `kubectl apply -k k8s/kustomize/sim`\n3. To install `skctl` on your dev machine: `cargo install skctl`\n\n## Documentation\n\nFull [documentation for SimKube](https://simkube.dev/documentation/) is available on the SimKube website.\nHere are some quick links to select topics:\n\n- [Installation](https://simkube.dev/simkube/docs/intro/installation/)\n- [Autoscaling](https://simkube.dev/simkube/docs/adv/autoscaling/)\n- [Metrics Collection](https://simkube.dev/simkube/docs/adv/metrics/)\n- [Developing SimKube](https://simkube.dev/simkube/docs/dev/contributing/)\n\n### Architecture Diagram\n\n![architecture diagram of SimKube](docs/images/sk-overview.png)\n\n## Community\n\nWe have a [channel](https://kubernetes.slack.com/archives/C07LTUB823Z) on the Kubernetes Slack instance!
