Add maestro documents and also the wiki pages.

Maestro looks great and seems really powerful, but it would be helpful to have a more detailed "Getting Started" guide or better documentation. The current README gives a basic overview, but more information on setup, usage examples, and advanced features would make it easier for new users to get up to speed.

Some suggestions:

A step-by-step guide for setup and running Maestro. More detailed examples of workflows and real-world use cases. Tips for troubleshooting and best practices. Thanks for the great work!
