How did you create and document the project documentation?

I created the project documentation using the following approaches:

• Technical documentation: described the architecture, technologies used, project structure, and key components.
• Comments in code: wrote clear and informative comments, especially for complex logic.
• Use of documentation generation tools: for example, XML comments in C# and documentation generation with Sandcastle or DocFX.
• README and instructions: created files with descriptions of installation, startup, and main usage scenarios.

This approach ensures the project is understandable for new team members and simplifies code maintenance.
