# Install Lunar

Welcome to the Lunar installation guide.

This section contains step-by-step instructions for installing Lunar. Install these pieces, in this order:

1. **Lunar CLI** – an admin and development CLI. Install this first: the Hub install walkthrough uses `lunar licence` to derive your GHCR image-pull secret from your licence JWT before `helm install`.
   * [Install the Lunar CLI](/install/cli.md)
2. **Lunar Hub** – the central coordination service.
   * [Overview](/install/lunar-hub/hub-overview.md) – the lay of the land: services, dependencies, ports.
   * [Prerequisites](/install/lunar-hub/hub-prereqs.md) – what to have in place before `helm install`.
   * [Install walkthrough](/install/lunar-hub/hub-install.md) – step-by-step from zero to a working Hub.
   * [Day-2 operations](/install/lunar-hub/hub-day2.md) – upgrades, secret rotation, observability, uninstall.
3. **Lunar CI Agent** — instruments your CI runners to report data to the Hub. Choose based on how your CI is set up:
   * [Self-hosted runners](/install/lunar-ci-agent/agent-self-hosted.md)
   * [GitHub-hosted managed runners](/install/lunar-ci-agent/agent-managed.md) (the [earthly/lunar-ci-action](https://github.com/earthly/lunar-ci-action)).

Optional:

* [`sync-config` GitHub Action](/install/github-actions.md) – pushes your config repo to Lunar Hub on every push.
* [AI Skills](/install/skills.md) – agent skills for building collectors and policies.
