# Join

### Overview

The **Join Component** is used to merge multiple input connections. It forwards every received message to the output port without modification.

### Usage

#### Input Ports

| Port | Description                              |
| ---- | ---------------------------------------- |
| `in` | Receives messages from multiple sources. |

#### Output Ports

| Port  | Description                                  |
| ----- | -------------------------------------------- |
| `out` | Emits the received input messages as output. |

### Instructions

1. **Connect Multiple Inputs**
   * Attach multiple input sources to the `in` port.
2. **Forward Messages**
   * Every received message is immediately sent to the `out` port.

### Notes

* **Does Not Modify Messages**: Messages are forwarded exactly as received.
* **Useful for Routing**: Can be used to merge multiple data streams into one processing path.
