📚 Documentation Directory

This directory serves as the central knowledge hub for Steam Dataset 2025, containing comprehensive technical documentation, methodological guides, and architectural specifications. Documentation covers everything from Steam API collection strategies to multi-modal database design, providing the detailed context needed to understand, validate, and extend the dataset.

Overview

The docs directory maintains systematic documentation across three major categories: technical architecture (database schemas, infrastructure specifications), analytical methodologies (data collection, validation, enrichment), and domain-specific guides (analytics reports, API schema analysis). This organization enables both human navigation and RAG system optimization through predictable structure and comprehensive knowledge graph connectivity.
