+## Handling concatenated CBOR
+
+By default, when decoder received concatenated CBOR, that raises error.
+
+```rb
+Cborb.decode("\x83\x01\x02\x03\x04") # => Cborb::InvalidByteSequenceError
+```
+
+If you want to decode concatenated CBOR, set `concatenated` option to `true`.  
+Decoder decodes whole of concatenated CBOR and returns instance of `Cborb::Decoding::Concatenated`.
+
+```rb
+results = Cborb.decode("\x83\x01\x02\x03\x04", concatenated: true)
+# => #<Cborb::Decoding::Concatenated:0x00007fcb1b8b2e30 @decoded=[[1, 2, 3], 4]>
+
+results.first # => [1, 2, 3]
+results.last  # => 4
