 ### Data type recommendations
 
-| Value type               | protobuf Type | Size / Notes
-|--------------------------|---------------|-----------------------------------------------------------------------------------
-| Unsigned 32 bit integers | uint32        | 1 to 5 bytes.
-| Signed 32 bit integers   | sint32        | 1 to 5 bytes. Do not use int32 (always encodes negative values as 10 bytes).
-| Unsigned 52 bit integers | uint64        | 1 to 10 bytes.
-| Signed 52 bit integers   | sint64        | 1 to 10 bytes. Do not use int64 (always encodes negative values as 10 bytes).
-| Unsigned 64 bit integers | uint64        | Use with long.js. 1 to 10 bytes.
-| Signed 64 bit integers   | sint64        | Use with long.js. 1 to 10 bytes. Do not use int64 (always encodes negative values as 10 bytes).
-| 32 bit precision floats  | float         | 4 bytes.
-| 64 bit precision floats  | double        | 8 bytes. Use float if 32 bits of precision are enough.
-| Boolean values           | bool          | 1 byte.
-| Strings                  | string        | 1 byte + utf8 byte length.
-| Buffers                  | bytes         | 1 byte + byte length.
