[cun3yt]

Overview

This PR adds comprehensive documentation for AgentDock, a powerful framework for building specialized AI agents. The tutorial breaks down the architecture into 8 well-documented components with clear explanations and mermaid diagrams for visual clarity.

Key Components Documented

• Agent Configuration system
• Tools integration framework
• Node architecture (BaseNode & AgentNode)
• LLM abstraction layer
• Orchestration management
• API routing implementation
• Session management system
• Storage provider architecture

Value Added

• Expands our collection of AI framework tutorials with a specialized agent-building framework
• Provides detailed insights into agent-based systems that complement existing examples like AutoGen and CrewAI
• Helps developers understand modern agent architecture patterns
• Maintains consistent documentation style with our existing tutorials

The documentation follows the project's established pattern of breaking down complex systems into beginner-friendly explanations, making it accessible for developers new to agent-based frameworks.
