+# WRACv2.0 Protocol
+
+Uses websocket for connections, and sends binary data only (works in packet-way manner)
+
+Totally inherits all packets of RACv2, except of reading messages
+
+## Sending messages
+
+Client sends:
+
+- Byte `0x01`
+- Message text
+
+## Sending authorized messages
+
+Client sends:
+
+- Byte `0x02`
+- Username
+- `\n`
+- Password
+- `\n`
+- Message
+
+Server sends:
+
+- nothing if message was sent successfully
+- `0x01` if the user does not exists
+- `0x02` if the password is incorrect
+
+## Registration users
+
+Client sends:
+
+- Byte `0x03`
+- Username
+- `\n`
+- Password
+
+Server sends:
+
+- nothing if user was registered successfully
+- `0x01` if the username is already taken
+
+## Reading messages
+
+### Getting message length
+
+Client sends:
+
+- Byte `0x00`
+
+Server sends:
+
+- Size of all messages in ASCII (data_size)
+
+### Normal reading
+
+This packet is independent from getting message length packet.
+
+Client sends:
+
+- Byte `0x00`
+- Byte `0x01`
+
+Server sends:
+
+- All messages
+
+### Chunked reading
+
+This packet is independent from getting message length packet.
+
+Client sends:
+
+- Byte `0x00`
+- Byte `0x02`
+- Size of messages you have in ASCII (last_size)
+
+Server sends:
+
+- All new messages
+
+*for example: if you want to read last N bytes, last_size = data_size - N*
