Improve Project Documentation Structure and Completeness

[CDiezRodriguez]

Description

As a developer or contributor,
I want clearer, more complete, and better-structured project documentation,
so that onboarding, development, and maintenance tasks can be performed more efficiently and with fewer misunderstandings.

Acceptance Criteria

• Review and identify outdated, missing, or unclear documentation sections
• Improve the structure and navigation of the documentation (README, guides, architecture, setup, etc.)
• Add or update setup, configuration, and deployment instructions
• Ensure examples are consistent and aligned with the current implementation
• Validate that documentation reflects the current project state

Additional Information

The goal is to make the documentation easier to follow for new contributors and more reliable for existing developers.
This may include improving installation steps, configuration explanations, architectural overviews, and usage examples.
