-## What are actors good for?
-
-Actors in ActorCore are ideal for applications requiring:
-
-- **Stateful Services**: Applications where maintaining state across interactions is critical. For example, **Collaborative Apps** with shared editing and automatic persistence.
-- **Realtime Systems**: Applications requiring fast, in-memory state modifications or push updates to connected clients. For example, **Multiplayer Games** with game rooms and player state.
-- **Long-Running Processes**: Tasks that execute over extended periods or in multiple steps. For example, **AI Agents** with ongoing conversations and stateful tool calls.
-- **Durability**: Processes that must survive crashes and restarts without data loss. For example, **Durable Execution** workflows that continue after system restarts.
-- **Horizontal Scalability**: Systems that need to scale by distributing load across many instances. For example, **Realtime Stream Processing** for stateful event handling.
-- **Local-First Architecture**: Systems that synchronize state between offline clients. For example, **Local-First Sync** between devices.
-
-## Core Concepts
-
-In ActorCore, each actor has these key characteristics:
-
-- **State Is Automatically Persisted**: State automatically persists between restarts, upgrades, & crashes
-- **State Is Stored In-Memory**: State is stored in memory for high-performance reads/writes while also automatically persisted
-- **Isolated State Ownership**: Actors only manage their own state, which can only be modified by the actor itself
-- **Communicates via Actions**: How clients and other actors interact with an actor
-- **Actions Are Low-Latency**: Actions provide WebSocket-like performance for time-sensitive operations
-- **Broadcast Updates With Events**: Actors can publish real-time updates to connected clients

 ## Code Example
 
 Here's a complete chat room actor that maintains state and handles messages. We'll explore each component in depth throughout this document:
