SerializationService:DeserializeInstancesAsync(buffer: buffer): { Instance }
```

Parameters:

- `buffer`: A [`buffer`](https://rapi.sleaze.dev/index/types/buffer.md) containing the `.rbxm` content to deserialize.

Returns: A list of the `instances` reconstructed from the buffer's `.rbxm` content.

### SerializeInstancesAsync

```luau
SerializationService:SerializeInstancesAsync(inputInstances: { Instance }): buffer
```

- Tags: Yields, Capabilities: PluginOrOpenCloud

Serializes a list of `instances` to the `.rbxm` format, returning a [`buffer`](https://rapi.sleaze.dev/index/types/buffer.md) or `.rbxm` content.

Parameters:

- `inputInstances`: The list of `instances` to serialize.

Returns: A [`buffer`](https://rapi.sleaze.dev/index/types/buffer.md) containing the `.rbxm` content of the serialized instances.
