 # Transports
 
-Unity Netcode for GameObjects (Netcode) uses Unity Transport by default and also provides a single player transport.
+Use a transport layer to establish communication between your application and different hosts in a network.
 
-## So what is a transport layer?
+Netcode for GameObjects uses [Unity Transport](https://docs.unity3d.com/Packages/com.unity.transport@latest) by default and also provides a [single player transport](#single-player-transport).
 
-The transport layer establishes communication between your application and different hosts in a network.
+## Introduction to transports
 
-A transport layer can provide:
-* *Connection-oriented communication* to ensure a robust connection before exchanging data with a handshake protocol.
-* *Maintain order delivery* for your packets to fix any discrepancies from the network layer in case of packet drops or device interruption.
-* *Ensure data integrity* by requesting retransmission of missing or corrupted data through using checksums.
-* *Control the data flow* in a network connection to avoid buffer overflow or underflow--causing unnecessary network performance issues.
-* *Manage network congestion* by mediating flow rates and node overloads.
-* *Adjust data streams* to transmit as byte streams or packets.
+A transport layer is a software layer that provides communication services between applications on different hosts in a network. It's responsible for establishing, maintaining, and terminating connections, and for delivering data according to the guarantees that the chosen protocol offers.
+
+Transport layers are essential for networked applications. Depending on the protocol and the delivery mode in use, a transport layer can provide the following features:
+
+- *Connection-oriented communication* to ensure a robust connection before exchanging data with a handshake protocol.
+- *Maintain order delivery* for your packets to fix any discrepancies from the network layer in case of packet drops or device interruption.
+- *Ensure data integrity* by requesting retransmission of missing or corrupted data through using checksums.
+- *Control the data flow* in a network connection to avoid buffer overflow or underflow, which can cause unnecessary network performance issues.
+- *Manage network congestion* by mediating flow rates and node overloads.
+- *Adjust data streams* to transmit as byte streams or packets.
+
+> [!NOTE]
+> Not all of these features apply to every message. Netcode for GameObjects supports both reliable and unreliable delivery through the `NetworkDelivery` modes, and messages sent as `Unreliable` or `UnreliableSequenced` can be dropped instead of retransmitted. Refer to [Reliability](./message-system/reliability.md) for more information.
 
 ## Unity Transport package
 
-Netcode's default transport Unity Transport is an entire transport layer that you can use to add multiplayer and network features to your project with or without Netcode. Refer to the Transport [documentation](https://docs.unity3d.com/Packages/com.unity.transport@latest) for more information and how to [install](https://docs.unity3d.com/Packages/com.unity.transport@latest?subfolder=/manual/install.html).
+Netcode for GameObjects uses the [Unity Transport](https://docs.unity3d.com/Packages/com.unity.transport@latest) package as its default transport layer. Unity Transport is a low-level networking library that provides a high-performance, cross-platform transport layer for multiplayer games and applications. It's designed to be flexible and extensible, allowing developers to implement custom transport protocols if needed.
 
-Netcode provides a [UnityTransport](xref:Unity.Netcode.Transports.UTP.UnityTransport) implementation for easy transport integration with Netcode.
+Netcode for GameObjects provides a [`UnityTransport`](xref:Unity.Netcode.Transports.UTP.UnityTransport) class you can use to configure and manage the Unity Transport package. This class provides a simple interface for setting up and managing network connections, as well as sending and receiving data.
 
 ## Single player transport
 
-Netcode also provides a [single player transport](./singleplayer.md) that allows for easy switching between multiplayer and single player configurations.

-The community transports are interchangeable transport layers for Netcode and can be installed with the Unity Package Manager. After installation, the transport package will appear in the **Select Transport** dropdown of the NetworkManager. Check out the [Netcode community contributed transports](https://github.com/Unity-Technologies/multiplayer-community-contributions/tree/main/Transports) for more information.
