  description: |
    A **complete DevOps platform** that provides Git repository management, CI/CD pipelines,
    issue tracking, and container registry in a single application.
    ## Prerequisites
    - ...
    **Performance Presets**:
    - `homelab`: Optimized for low-resource environments (limited workers, reduced PostgreSQL buffers)
    - `default`: Standard server configuration for production use
    **External URL**:
    - Set to your public domain (e.g., `https://gitlab.example.com`) for proper clone URLs
    - Affects SSH clone URLs and web links in emails/notifications
    **Container Registry**:
    - Enable if you need private Docker image hosting
    - Requires separate external URL (e.g., `https://registry.example.com`)
