+## Architecture and Design
+
+1. **System Architecture:**
+    * Overview of the system architecture:
+      The Skyenet LLM Agent Platform is designed with a modular architecture to support real-time, interactive applications leveraging large language models. The core components include the LLM manager, session management, and dynamic content rendering. The system leverages LLMs for real-time interaction between the client and server, ensuring low latency and high
+      responsiveness. The architecture is divided into several layers: the presentation layer (UI components), the
+      application layer (session and task management), and the data layer (storage and retrieval of user data and
+      settings).
+
+    * Diagrams (if any):
+      ![System Architecture Diagram](path/to/diagram.png)  // Add a path to the actual diagram if available
+
+2. **Design Patterns:**
+    * What design patterns are used?
+      The Skyenet LLM Agent Platform employs several design patterns to ensure a robust and maintainable codebase:
+
+ **Observer Pattern**: Used in the LLM manager to handle real-time updates and notifications.
+ **Factory Pattern**: Utilized for creating instances of various components like session tasks and UI elements.
+ **Singleton Pattern**: Ensures a single instance of core managers like `ApplicationServices`
+    - **Observer Pattern**: Used in the WebSocket manager to handle real-time updates and notifications.
+    - **Factory Pattern**: Utilized for creating instances of various components like session tasks and UI elements.
+    - **Singleton Pattern**: Ensures a single instance of core managers like `ApplicationServices`
+      and `SocketManagerBase`.
+ **Strategy Pattern**: Allows for flexible implementation of different retry mechanisms in the `Retryable` class.
+ **Decorator Pattern**: Used to extend the functionality of UI components dynamically.
+    - **Strategy Pattern**: Allows for flexible implementation of different retry mechanisms in the `Retryable` class.
+    - **Decorator Pattern**: Used to extend the functionality of UI components dynamically.
+
+    * Why were they chosen?
+      These design patterns were chosen to promote code reusability, flexibility, and separation of concerns. The
+      Observer Pattern is ideal for real-time LLM interaction scenarios, while the Factory Pattern simplifies the creation
+      of complex objects. The Singleton Pattern ensures efficient resource management, and the Strategy Pattern allows
+      for easy customization of retry logic. The Decorator Pattern enables dynamic enhancement of UI components without
+      modifying their core functionality.
+
+3. **Technology Stack:**
+    * List of technologies and frameworks used:
+
+    - **Frontend**: HTML, CSS, JavaScript, and Kotlin for the UI components and LLM interactions.
+    - **Backend**: Kotlin for server-side logic, leveraging Ktor for building asynchronous servers and managing LLM interactions.
+    - **LLMs**: Used for real-time interaction between the client and server.
+    - **Database**: HSQLDB for usage tracking, data storage, and managing LLM interactions.
+ **Cloud Services**: AWS S3 for file storage, AWS KMS for encryption.
+ **CI/CD**: GitHub Actions for continuous integration and deployment, Docker for containerization.
+    - **Cloud Services**: AWS S3 for file storage, AWS KMS for encryption.
+    - **CI/CD**: GitHub Actions for continuous integration and deployment, Docker for containerization.
+
+    * Reasons for choosing these technologies:
+      The chosen technologies and frameworks provide a balance of performance, scalability, and developer productivity. Kotlin is used for both frontend and backend development to ensure consistency and leverage its modern language features. Ktor is selected for its lightweight and asynchronous capabilities, making it suitable for real-time LLM interactions. LLMs are essential for maintaining low-latency communication. HSQLDB is chosen for its
+      simplicity and ease of integration. AWS services are utilized for their reliability, security, and scalability.

+    * **ApplicationInterface**: Provides methods to create interactive HTML elements and manage tasks. It acts as a
+      bridge between the task management logic and the LLM communication layer.
+    * **SessionTask**: Represents a task that can display progress and messages. It allows for dynamic updates to the UI
+      as tasks progress.
+    * **TabbedDisplay**: Manages a tabbed interface for displaying content. It supports adding, updating, and rendering
+      tabs dynamically.
+    * **Retryable**: Extends `TabbedDisplay` to add a retry mechanism for tasks. It allows for re-running a block of
+      code and capturing the new output in a new tab.
+    * **AgentPatterns**: Provides utility functions for displaying content in tabs. It helps in organizing and rendering
+      content efficiently.
+    * **Discussable**: Facilitates interactive discussions with users, allowing for feedback and revisions. It manages
+      user interactions and refines responses based on feedback.
+    * **UserSettingsManager**: Manages user settings, including loading and saving settings to disk. It ensures that
+      user preferences are maintained across sessions.
+    * **ClientManager**: Manages API clients, including creating and caching clients for sessions and users. It handles
+      the lifecycle of API clients and ensures efficient resource usage.
+    * **HSQLUsageManager**: Manages usage tracking using an HSQL database. It tracks resource usage and provides
+      summaries for monitoring and billing purposes.
+    * **AuthorizationManager**: Manages user authorization, checking if a user is authorized for specific operations. It
+      enforces access control policies.
