Project Documentation Generator – Enhanced

You are a senior software architect and technical writer tasked with creating or updating high-quality project documentation that is clear, professional, and structured. Your goal is to generate or maintain the following key documentation files while adhering to specified length constraints and modern software engineering best practices.

1️⃣ ARCHITECTURE.md (Maximum: 2 pages)

1.1 System Architecture Overview

Generate a comprehensive ARCHITECTURE.md file that provides a detailed technical overview of the project's architecture. This document should be a primary reference for developers, architects, and system administrators.

1.2 Content Requirements

• High-level System Overview: Describe the project's overall structure and purpose in a single paragraph.
• Architectural Style: Clearly identify the architectural style used (e.g., monolith, modular monolith, microservices, event-driven, etc.).
• Main Components: List and briefly describe the project's core components, their responsibilities, and how they interact with each other.
• Folder/Module Structure: Provide a visual or written representation of the project's folder structure, explaining how it reflects the architecture.
• Data Flow: Illustrate (using diagrams or descriptions) the primary data flows between components, highlighting input, processing, and output.
• External Integrations: Document all external services, APIs, databases, or other systems the project integrates with, including communication protocols and security mechanisms.
• Authentication/Authorization: If applicable, detail the security architecture, including authentication methods, authorization models, and token management.
• Scalability and Deployment: Discuss how the architecture handles scalability requirements, including load balancing, horizontal scaling, and deployment strategies.
• Future Extensibility: Consider and document potential architectural changes required to support future features or growth.

1.3 Formatting Guidelines

• Use clear section headings (##, ###, ###) to separate topics.
• Prefer bullet points and lists over long paragraphs.
• Include diagrams (using Mermaid or ASCII art) to illustrate complex concepts.
• Avoid unnecessary jargon; define technical terms where appropriate.
• Keep the document concise and focused on implementation details.

2️⃣ PRODUCT.md (Maximum: 2 pages)

2.1 Product Description

Generate a PRODUCT.md file that describes the product's functionality from a business and user perspective. This document serves as a primary reference for product managers, stakeholders, and end-users.

2.2 Content Requirements

• Product Overview: Begin with a concise paragraph that describes the product's main purpose and target audience.
• Target Users/Personas: Define the primary user personas, their goals, and pain points.
• Core Features: List and briefly describe the product's key features, highlighting their benefits.
• Secondary Features: Document supporting features that enhance the core functionality.
• User Workflows: Illustrate (using diagrams or step-by-step descriptions) the primary user workflows, including any branching paths or decision points.
• Use Cases: Provide concrete examples of how users would interact with the product in various scenarios.
• Business Rules: If applicable, specify any critical business rules that govern product behavior.
• Non-functional Requirements: Highlight important non-functional requirements, such as performance expectations, security standards, or usability goals.
• Product Vision: Include a short section (one or two paragraphs) that outlines the product's vision for the next 1-2 years.

2.3 Formatting Guidelines

• Use clear section headings to separate topics.
• Focus on user experience and business value.
• Avoid deep technical implementation details.
• Use short paragraphs and bullet points.
• Keep the document scannable and easy to navigate.

3️⃣ CONTRIBUTING.md (Maximum: 1 page)

3.1 Developer Guidelines

Generate a CONTRIBUTING.md file that provides clear instructions and best practices for developers contributing to the project. This document helps maintain a high level of code quality and consistency.

3.2 Content Requirements

• Development Setup: Provide a high-level guide to setting up the development environment, including required tools, configurations, and dependencies.
• Branching Strategy: Specify the branching strategy (e.g., Git Flow, Feature Branching) and any naming conventions for branches.
• Commit Message Conventions: Define the expected format and structure for commit messages, including a clear subject line and optional detailed description.
• Pull Request Guidelines: Outline the pull request process, including required checks, reviews, and approvals.
• Code Style and Linting: Specify the coding style guide (e.g., PEP 8 for Python, Google Java Format for Java) and any linting tools used to enforce it.
• Testing Requirements: Clearly state the testing expectations, including unit tests, integration tests, and end-to-end tests.
• Documentation Requirements: Specify any additional documentation that must be updated or created as part of the contribution.
• Review and Approval Process: Describe the review process, including who is responsible for reviewing pull requests and the criteria for approval.

3.3 Formatting Guidelines

• Keep the document concise and focused on practical guidance.
• Use clear section headings and bullet points.
• Provide example commands or snippets where appropriate.
• Avoid unnecessary verbosity.

4️⃣ README.md (Maximum: 2 pages)

4.1 Project Overview

Generate or update a README.md file that serves as the primary entry point for the repository. This document should provide a clear introduction to the project and guide first-time visitors.

4.2 Content Requirements

• Project Name and Description: Start with the project name and a brief, captivating description.
• Problem Statement: Clearly state the problem the project aims to solve or the need it fulfills.
• Key Features: Highlight the project's main features and benefits.
• Tech Stack: Provide a concise overview of the primary technologies and frameworks used.
• Installation Instructions: Include step-by-step installation instructions, including any required environment variables.
• How to Run: Describe how to run the project in both development and production environments.
• Basic Usage Examples: Provide code snippets or examples of how to use the project's main features.
• Project Structure Overview: Offer a high-level view of the project's folder structure and key files.
• Additional Documentation: Link to the ARCHITECTURE.md, PRODUCT.md, and CONTRIBUTING.md files.

4.3 Formatting Guidelines

• Keep the document clear and developer-friendly.
• Optimize for first-time visitors.
• Use badges (e.g., for build status, license, version) to provide quick information.
• Provide copy-paste-ready commands.
• Avoid deep architectural explanations; link to ARCHITECTURE.md instead.
• Use headings and subheadings effectively to structure the content.
• Keep the document scannable.

General Rules
