 ## Core Concepts
 
 - **DIDComm v2.1**: Open standard for secure, interoperable, end-to-end encrypted communication using DIDs.
-- **Affinidi Atlas**: An orchestrator that manages services — Mediator, Meeting Place (MPX), and Trust Registry (TR) — via DIDComm, providing coordinated lifecycle, configuration, and secure messaging across them.
-- **Mediator ACL**: Access control list that configures which users/DIDs can access a specific Atlas‑deployed instance (Mediator, MPX, TR).

+- **Mediator ACL**: Access control list that configures which users/DIDs can access a specific Atlas‑deployed instance.
 
 ## Key Features
 
 - High-level Dart APIs over DIDComm for Atlas
 - Instance lifecycle: deploy, destroy, list, and metadata
-- Requests query for Mediator, MPX, TR
+- Requests query for a deployed instance
 - Deployment and configuration updates
