+# Server-Side Networking — How It All Fits Together
+
+This doc is meant to give a solid mixed-level understanding of how our server-side networking works. No deep dives — just a clear picture of what's happening under the hood when a client connects and sends a command.
+
+> **Note:** This is v1. Annotations and Reflection-based dispatching are on the roadmap but not covered here yet.
+
+> **Disclamer:** This document has been written by Claude. I modified certain parts and verified its contents for correctness.
+
+## Our Protocol at a Glance
+
+Our protocol is inspired by **POP3** - a classic, text-based protocol that communicates over a raw TCP connection. The idea is simple: the client sends a command as a plain-text string, and the server responds with either a success or an error.
+
+A typical exchange looks something like this:
+
+```
+Client  →  GET_DELTA SINCE=42
+Server  →  +OK
+           PLAYER_FOLDED playerId=3
+           POT 240
+           NEXT_TURN playerId=1
+           .
+```
+
+Responses start with `+OK` on success or `-ERR` when something goes wrong. Commands are short, uppercase strings - sometimes followed by arguments.
+
+We don't use HTTP, there's no JSON body, no headers. Just a raw socket, a text stream, and a clearly defined set of commands.
+
+## Core Components & Their Roles
+
+![PlantUML diagramm of all components outlined in this document](/documents/images/docs/networking/server-architecure/networking_components.svg)
+
+Here's a quick rundown of the main building blocks:
+
+### `NetworkManager`
+This is the entry point. It binds to a specific port and listens for incoming TCP connections.
+Once a client connects, it creates a `Session` adds it to the `SessionManager` and goes back to waiting. Its not the responsibility of the `NetworkManager` to recieve and send data from and to each connected client.
+
+### `Session`
+Every client that connects has its own `Session` instance running on its own thread. This component owns the lifecycle of that connection: it reads incoming data, passes it along for processing, and writes responses back.
+
+###  `SessionId`
+The `SessionId` is used to uniquely identify each session. Essentially its a wrapper arround the UUID type.
+
+### `SessionManager`
+The `SessionManager` stores all currently active sessions. It allows for the retrieval of a specific session by its id.
+
+### `ProtocolParser`
+Raw text (encapsulated in a `RawRequest`) coming off the socket isn't immediately useful — the `ProtocolParser` turns it with the help of the `Tokenizer` into a `PrimitiveRequest`.
+
+### `RawRequest`
+The `RawRequest` object is created after a message has been recieved.
+It holds both a reference to the `Session` that recieved the message and the message itself.
+
+### `PrimitiveRequest`
+The `PrimitiveRequest` object is created by the `ProtocolParser` after the content of the `RawRequest` has been tokenized by the `Tokenizer`.
+The command is stored in its own attribute and the arguments are accessible as a dictionary.
+
+### `Tokenizer`
+The job of the `tokenizer` is it, to take the raw string and turn it into tokens. 
+For example, the command `CHAT_LOBBY GAME=12 MESSAGE='All-in?'` will be decoded as `"CHAT_LOBBY", "GAME", "=", "12", "MESSAGE", "=", "All-in?"`.
+It is unaware about the meaning.
+
+### `CommandParser` (per command)
+Takes in the `PrimitiveRequest` and checks if all required fields are provided with the correct value.
+Creates a command specific `Request` object containing command arguments in a structured manner.
+
+### `Request` (per command)
+Has fields common along each implementation such as a reference to the `Session` that recieved the request.
+Furthermore each implementation has fields unique to each command. For example, the `ChatLobbyRequest` has fields for the game and the message.
+
+### `CommandRouter`
+By identifying the type of class of the `Request`, the `CommandRouter` routes the request to the matching `CommandHandler`.
+
+### `CommandHandler` (per command)
+Each supported command has its own handler — a small, focused class that contains the logic for that specific command. They have access to the domain, containing inner parts of the game itself.
+
+### `Response` (per response)
+The interface has two sub-interfaces for either failed `ErrorResponse` or successfull `SuccessResponse` execution of commands.
+
+Each step has exactly one responsibility. Increasing the ability to test and extend different components later on.
+
+## Concurrency - Handling Multiple Clients
+
+Every incoming connection spawns a new **Thread**. This means multiple clients can be served simultaneously without blocking each other.
+
+As each `Session` runs entirely on its own thread, there's no shared mutable state between sessions, with exception of the `SessionManager` and other key components explained later.
