This repository contains the public information and learning resources for DigitalPlat FreeDomain, a free domain registration service. It includes a comprehensive book-length tutorial covering domain registration, DNS, website building, HTTPS, email records, operations, and security. The actual application source code is maintained separately in DigitalPlatDev/Domain-OSS. This repo is purely documentation and educational material, with no executable code or data pipelines. It serves as a guide for users to register and manage domains using DigitalPlat's service and external DNS providers. The documentation is well-structured, with clear separation between product-specific instructions and general textbook content, and includes practical exercises, checklists, and troubleshooting guides.
