+# Serialization for `DocVec`
+When sending or storing `DocVec`, you need to use serialization. `DocVec` only supports protobuf to serialize the data.
+You can use `to_protobuf()` and `from_protobuf()` to serialize and deserialize a `DocVec`
+
+```python
+import numpy as np
+
+from docarray import BaseDoc, DocVec
+from docarray.typing import AnyTensor
+
+
+class SimpleVecDoc(BaseDoc):
+    tensor: AnyTensor
+
+
+dv = DocVec[SimpleVecDoc]([SimpleVecDoc(tensor=np.ones(16)) for _ in range(8)])
+
+proto_message_dv = dv.to_protobuf()
+
+dv_from_proto = DocVec[SimpleVecDoc].from_protobuf(proto_message_dv)
+```
+
+`to_protobuf()` returns a protobuf object of `docarray_pb2.DocVecProto` class. `from_protobuf()` accepts a protobuf message object to construct a `DocVec`.
