+# Binary Serialization Format
+
+### Introduction
+
+Godot has a simple serialization API based on Variant. It's used for converting data types to an array of bytes efficiently. This API is used in the functions [File.get_var](class_file#get_var), [File.store_var](class_file#store_var) as well as the packet APIs for [PacketPeer](class_packetpeer). This format is not used for binary scenes and resources.
+
+### Packet Specification
+
+The packet is designed to be always padded to 4 bytes. All values are little endian encoded. 
+All packets have a 4 byte header with an integer, specifying the type of data:
+
+Type | Value
+0 | null
+1 | bool
+2 | integer
+3 | float
+4 | string
+5 | vector2
+6 | rect2
+7 | vector3
+8 | matrix32
+9 | plane
+10| quaternion
+11| aabb (rect3)
+12| matrix3x3
+13| transform (matrix 4x3)
+14| color
+15| image
+16| node path
+17| rid (unsupported)
+18| object (unsupported)
+19| input event
+20| dictionary
+21| array 
+22| byte array
+23| int array
+24| float array
+25| string array
+26| vector2 array
+27| vector3 array
+28| color array
+
+Following this is the actual packet contents, which varies for each type of packet:
+
+### 0: null
+### 1: bool
+### 2: integer
+### 3: float
+### 4: string
+### 5: vector2
+### 6: rect2
+### 7: vector3
+### 8: matrix32
+### 9: plane
+### 10: quaternion
+### 11: aabb (rect3)
+### 12: matrix3x3
+### 13: transform (matrix 4x3)
+### 14: color
+### 15: image
+### 16: node path
+### 17: rid (unsupported)
+### 18: object (unsupported)
+### 19: input event
+### 20: dictionary
+### 21: array 
+### 22: byte array
+### 23: int array
+### 24: float array
+### 25: string array
+### 26: vector2 array
+### 27: vector3 array
+### 28: color array
