## Structure
This product documentation platform is based on BookStack, which uses the hierarchical structure of a library to categorize content:
- **Shelves**: Product families which consist of individual products that are intended to be combined (examples: true-Xtender, true-Sign)
- **Books**: Single product containing manuals, realeases and more (examples: true-Xtender Registration Authority, true-Sign Crypto Service)
- **Chapters**: A collection of the same document type available for different product versions (examples: Manuals, Releases)
- **Pages**: The individual document containing content of a product about a specific version (examples: Introduction, User Manual V-1.0.0, Release V-1.0.0)
