[Feature Request]: Write a basic "Getting Started" Guide in the README

[alckasoc]

Feature Description

This guide should:

• concise but clearly showcase this library's uses
• demonstrate the overall library structure
• what the library provides and what it doesn't
• simple use case with defining a module (any module or all; though keep it minimal, this is a getting started guide)
• simple use case defining an agent (ReAct is a good start)
• running an agent on sample input
