            ## Installation

            ### Quick Install (Linux/macOS)

            ```bash
            curl -sSL https://raw.githubusercontent.com/shankar0123/certctl/master/install-agent.sh | bash
            ```

            ### Manual Binary Download

            Download the appropriate binary for your OS and architecture:

            - **Linux x86_64**: `certctl-agent-linux-amd64`
            - **Linux ARM64**: `certctl-agent-linux-arm64`
            - **macOS x86_64**: `certctl-agent-darwin-amd64`
            - **macOS ARM64 (Apple Silicon)**: `certctl-agent-darwin-arm64`

            Then make it executable and start the service:

            ```bash
            chmod +x certctl-agent-linux-amd64
            sudo mv certctl-agent-linux-amd64 /usr/local/bin/certctl-agent
            ```

            ## Docker Images

            Pull pre-built Docker images for server and agent:

            ```bash
            docker pull ghcr.io/shankar0123/certctl-server:${{ steps.version.outputs.VERSION }}
            docker pull ghcr.io/shankar0123/certctl-agent:${{ steps.version.outputs.VERSION }}
            ```

            Or use the latest tag:

            ```bash
            docker pull ghcr.io/shankar0123/certctl-server:latest
            docker pull ghcr.io/shankar0123/certctl-agent:latest
            ```

            ## Docker Compose Quick Start

            ```bash
            git clone https://github.com/shankar0123/certctl.git
            cd certctl
            cp deploy/.env.example deploy/.env
            docker compose -f deploy/docker-compose.yml up -d
            ```

            ## Server Binaries

            Pre-compiled server binaries are also available for direct installation:

            - **Linux x86_64**: `certctl-server-linux-amd64`
            - **Linux ARM64**: `certctl-server-linux-arm64`

            ## Helm Chart

            Deploy certctl to Kubernetes using Helm:

            ```bash
            helm repo add certctl https://github.com/shankar0123/certctl/tree/master/deploy/helm
            helm repo update
            helm install certctl certctl/certctl
            ```

            See `deploy/helm/certctl/` for values customization.
