How did you document and store documentation for your project?

For documenting and preserving project documentation, I used the following approaches:

• README.md — the main file with project description, installation, and usage instructions.
• Code documentation — comments and docstrings for functions and classes to facilitate understanding of the code.
• Documentation generation tools — for example, Sphinx for Python, which allows creating readable documentation from docstrings.
• Version control system storage — documentation along with code in Git to track all changes.
• Wiki or internal portals — for more detailed documentation, architecture descriptions, and processes.

This approach helps keep the documentation up-to-date and accessible to the entire team.
