Docs: Review and integrate new official documentation

[bzantium]

Description

I have created an initial draft for the array_record documentation, which is now hosted on ReadTheDocs:

https://array-record.readthedocs.io/en/latest/

This issue is to track the process of reviewing, revising, and formally adopting this as the official documentation for the project.

Tasks

• Review the current draft for accuracy, clarity, and completeness.
• Identify any missing sections or topics that need to be added.
• Discuss and implement necessary revisions based on feedback.
• Formally integrate the documentation (e.g., link from the README, set up CI/CD for doc builds if needed).

Thanks. Still occupied by my main project but I'll soon get to it.
