## What it is [#what-it-is]

The PaaS SDK path gives teams more control over business logic, room interaction, and UI design while still building on Agora's real-time and music-related capabilities.

## Best fit [#best-fit]

* teams that want deeper customization
* products with existing app-specific room logic or UI systems
* engineering teams comfortable integrating RTC, RTM, and karaoke workflows directly

## Current status in this repo [#current-status-in-this-repo]

The detailed source materials for this path already exist under the legacy `online-ktv` content tree and will be migrated into this new directory model incrementally.
