-TAS server protocol
+TAS protocol
 ===================
 
-Connect to a TCP socket on localhost:6555.
+The following specification lists packets that can be sent between the player (SAR client capable of playing TAS scripts) and controller (external software capable of controlling the player through the protocol like VSC extension or bruteforcer server)
+SAR (the player) can act as both the client (connecting to a controller server) and server (listening for controller client connections).
 
 Every packet consists of a one-byte (u8) ID, followed by some extra data. the extra data is specified here under the packet name; if there's nothing specified, there's no extra data.
 
 The server should always send a packet with ID 255 first; it'll never send this again.
