+## Managing Factorio mods
+
+Clusterio currently only provides a manual method for running mods on servers by copying them either to each instance's individual `mods` folder, or by copying them into a slave installation's `sharedMods` folder which will link/copy them to the `mods` folder of each instance on that slave if the file doesn't already exist in the `mods` folder for that instance.
+Mods are copied from `sharedMods` on Windows and symlinked on Linux, this means that when mods are removed from `sharedMods` the mods will also be removed from the instance's `mods` folder on Linux if it got there by being linked by Clusterio, but not on Windows.
+
+For managing the mod settings the `mod-settings.dat` and `mod-list.json` files will also be linked/copied over if present in `sharedMods`, but since Factorio creates these files automatically it might be necessary to delete them from each instance's `mods` folder for changes to them in `sharedMods` to take effect.
+
+Better remote management of mods is a planned feature.
+
+
+## Setting up shared storage
+
+The chests teleporting items to and from the shared storage on the master server has been moved into the Subspace Storage mod and plugin.
+To get this to work you will need to install the Subspace Storage plugin and copy the [Subspace Storage mod](https://mods.factorio.com/mod/subspace_storage) and the [Clusterio Lib mod](https://mods.factorio.com/mod/clusterio_lib) into the `sharedMods` folder on each slave installation.
+
+Do not install the [Clusterio mod](https://mods.factorio.com/mod/clusterio), this was for the old 1.2.x version of Clusterio and is not compatible with Clusterio 2.0.

 The basics of setting up a Factorio server from the web interface is to create an instance, assign it to a slave and then click start.

+### Running via Systemd
+
+The install script creates systemd service scripts for clusteriomaster and clusterioslave (if applicable) to start up as the user than ran the installer.
+If you have copied these files over to `/etc/systemd/system/` then you can startup clusterio as a background service using:
+    
+#### To start as a service run:
+ 
+    sudo systemctl start clusteriomaster # for the master server
+    sudo systemctl start clusterioslave # for each server hosting a slave
+
+#### To automatically get it to start on boot:
+ 
+    sudo systemctl enable clusteriomaster # for the master server
+    sudo systemctl enable clusterioslave # for each server hosting a slave

+# Protocol
+
+Clusterio communicates using a simple homebrew message passing protocol based on JSON over WebSocket with limited support for reliable transport of messages.
+The protocol is implemented in [packages/lib/link](/packages/lib/link) and uses the `ws` library to handle the WebSocket connections on the Node.js side and the native WebSocket API on the browser side.
+
+Two general kinds of messages are supported: events and requests.
+Events are messages sent by one party and received by the other and offer no notification for the sender on whether it was actually received.
+Requests are pairs of request-response messages where one side sends the requests and the other side replies with a response.
+Apart from the handshake used to establish connections the protocol is directionless, and either party can send or receive both requests and events.
+
+Events and requests are defined as instances of the `Request` and `Event` classes, and specify a unique type string, who can send and receive the message, optional forwarding of the message and the format of the data payload as a JSON schema.
+All messages sent and received are validated with JSON schemas to catch potential errors in sending messages and avoid having to write lots of validation code in message handlers.
+
+Messages are sent by calling the `.send()` method of the message instance and passing a `Link` instance to send it over and the data to send.
+For the master server there's a `Link` instance for each slave and control connection stored in the `WsServer` class.
+For slaves the `Slave` instance is a link to the master server, and each `Instance` instance is an in-memory link to the `Slave` instance and has a corresponding `InstanceConnection` link stored on the `Slave` instance.
+For ctl and web_ui there's a `Control` instance that acts as the link to the master server.
+
+Messages received invokes message handlers that were registered when the link was brought up.
+These handlers are named after the name of the property the message is stored under with `EventHandler` appended for events and `RequestHandler` appended for requests.
+The handlers are defined on the link class itself for core messages, and on the plugin class in the case of plugin defined messages.
+
+
+## Connection flow
+
+Clients connect via WebSocket to the `/api/socket` endpoint and upon establishing connection to the server the connection is in the handshake phase and the server will send a `hello` message to the client.
+If the client has no previous session with the server it sends a `register_slave` or `register_control` message depending on what kind of client it is to the server.
+If the register is valid then the server will respond with a `ready` message with a session token and the connection has left the handshake phase, otherwise the server will close the connection with a WebSocket close code indicating the kind of failure.
+
+Upon leaving the handshake phase both parties should start sending heartbeat messages with the sequence number of the last received message.
+Messages sent over the link should be stored in a send buffer and only cleared from the send buffer when a heartbeat with a `last_seq` equal or or higher is received or the session is invalidated.
+
+If the connection goes stale or is unexpectedly closed the client can reastablish the same session by connecting to the server again and sending a `resume` message after received the `hello` from the server.
+If the session resume is successful then the server will respond with a `continue` message and the connection is active again.
+The client should then re-send all messages it has in its send buffer that is greater than the `last_seq` number in the `continue` message.
+Otherwise the server will respond with `invalidate` and the client is expected to drop its send buffer start a new session with `register_slave` or `register_control`.
+
+![Connection flow](../assets/connection_flow.svg)
+
+
+## Connector flow
+
+To manage the complexity of connecting, reconnecting, resuming or invalidating dropped sessions the WebSocket connection for a `Link` class is managed by a connector.
+There's three kinds of connectors defined: `WebSocketClientConnector`, `WebSocketServerConnector` and `VirtualConnector`.
+The virtual connector is for in-memory connections and doesn't have any connection state logic.
+
+For the WebSocket connectors there's four states they can exist in:
+- `closed` - The connector has just been created or has been explicitly closed.
+- `connecting` (client only) - The connector is in the process of trying to connect to the server.
+- `connected` - The connector is successfully connected.
+- `resuming` - The connection dropped and the connector is in the process of attempting to resume it.
+
+Along with the following events emitted when transition between states:
+- `connect` From `connecting` (client) or `closed` (server) to `connected`
+- `drop` - From `connected` to `resuming`
+- `resume` - From `resuming` to `connected`
+- `invalidate` - From `resuming` to `connecting` or `closed`
+- `close` - From any state to `closed`
+
+![Conector States](../assets/connector_states.svg)
+
+
+### WsClientConnector
+
+The client connector will keep trying to establish and mantain a connection after `.connect()` is called on it, stopping only in the case of authentication failure or `.close()`/`.setClosing()` being called.
+Other than that, the logic is pretty straight forward.
+
+![WsClientConnector](../assets/WsClientConnector.svg)
+
+
+### WsServerConnector
+
+The server connector doesn't do the work of connecting or validating the handshake.
+Instead it's handed over a WebSocket connection from `WsServer` once there's only the step of sending the final message left to do.
+Because of this there's no `connecting` state, and once a session times out from the `resuming` state it goes directly to closed.
+
+![WsServerConnector](../assets/WsServerConnector.svg)
+
+
+## Wire format
+
+All communication in the protocol is done via WebSocket text frames containing a JSON payload with the following properties:
+
+- `seq: integer | null` - The sequence number of the message, can only be null for handshake and heartbeats.
+- `type: string` - The type of message
+- `data: object` - Message data
+
+Before a connection is established it's in the handshake phase and the `seq` property is `null`.
+The `type` property is used to distinguish which of handshake, heartbeat, events or requests this message is and determines the expected format of the `data` property.
+
+
+### Handshake Messages
+
+The following messages are the only valid messages that can be sent during the handshake phase.
+
+
+#### `hello`
+
+Sent by the master server when the WebSocket connection has been opened.
+
+- `version: string` - The version of the master, e.g. "2.0.0".
+- `plugins: Object<string, string>` -
+    Object mapping plugin names to plugin version for plugins that are loaded on the master server.
+
+#### `register_slave`
+
+Slave handshake for establishing a new connection session.
+
+- `token: string` - Authentication token.
+- `agent: string` - Human readable string of the software connecting.
+- `version: string` - The protocol version of the slave, e.g. "2.0.0".
+- `name: string` - Name of the slave.
+- `id: integer` - ID of the slave.
+- `plugins: Object<string, string>` -
+    Object mapping plugin names to plugin version for plugins that are available on the slave.
+
+#### `register_control`
+
+Control handshake for enstablishing a new connection session.
+
+- `token: string` - Authentication token.
+- `agent: string` - Human readable string of the software connecting.
+- `version: string` - The protocol version of the control, e.g. "2.0.0".
+
+#### `resume`
+
+Handshake for resuming an existing connection session where the connection had dropped unexpectedly.
+
+- `session_token: string` - Session token to resume session with.
+- `last_seq: integer | null` - Last message seq received by the client.
+
+#### `invalidate`
+
+Sent by the master server in reply to a resume for a session that cannot be resumed.
+The client should start a new session with a register\_\* message in response.
+
+#### `continue`
+
+Sent by the master server to signal resuming the session was successful.

+
+Once connected as indicated by the `ready` and `continue` messages both sides of the connection starts sending heartbeats at the inverval given in the `ready` and `continue` messages.

+
+### Graceful Disconnect
+
+To ensure no data is lost when closing the link it's important to send a prepare disconnect request and wait for it to complete before closing the WebSocket.
+Either party of the link can send this request and the party sending the request should be the one that initates the close of the WebSocket.
+
+#### `prepare_disconnect_request`
+
+Request graceful disconnect of the connection.
+The receiving party should stop tasks that send events and requests over the link and wait for pending requests it has over the link to complete, but it should not stop responding to requests sent to it.
+Only after this process is done should the response be sent.
+
+#### `prepare_disconnect_response`
+
+Signals the preparation for disconnect is complete and that the connection can be closed.
+The party that initiatied the prepare disconnect request may still send other requests/events over the link to finish its part of the disconnection proceedure.
+
+If the error response variant is received it should be logged if possible and treated as a success.

-# WebSocket protocol
-
-<sub>This document describes the protocol used between the master and slaves, and unless you're developing Clusterio it's probably not going to be very useful for you.</sub>
-The protocol is built on WebSocket and uses JSON encoded text messages to communicate to and from the master server.
-These messages contain a JSON encoded object with the following three properties:
-
- seq - integer|null - The sequence number of the message
- type - string - The type of message
- data - object - Message data
-
-For the handshake and heartbeats the seq property is null.
-
-
-## Handshake
-
-Upon connecting to the WebSocket endpoint the server will respond with a `hello` message containing the master server version as the data.
-The client is then expected to send either `register_*` or a `resume` message to set up the connection with the master.
-The exact flow is described below.
-
-
-### Client connection flow
-
-For a client making a new connecting to the master server the first course of action after obtaining a token is to connect with WebSocket to the /api/socket endpoint and wait for the server hello.
-After the hello, the client sends a register\_\* message corresponding to the type of the client.
-If successful the server will reply with a ready message and the connection has been established.
-See the flowchart below.
-
-![Client connection flowchart](assets/connection_flow.svg)
-
-If for any reason the connection is closed or lost during the connection attempt the process is started over after a random delay, with the exception of the connection being closed with a 4003 code which means authentication failed and the client should stop trying to connect.
-The wait for hello and wait for ready states should also have a timeout, after which the connection is closed if the hello/reply wasn't received
-in time.
-
-
-### Client reconnection flow
-
-If the connection is lost after the client has received the ready message from the server it should attempt a reconnect instead.
-This is very similar to a new connection, but instead of a register\_\* messsage the client sends a resume message and the server replies with a continue message if resuming the session was successful.
-This continue message has sequence number of the last message the master received and the client is expected to imediately send all messages from its send buffer that occured after the sequence number given.
-
-The server will respond with an invalidate message if resuming the session is not possible.
-In this case the client should continue from the new session state of the connection flow (see the previous section).
-
-![Client reconnection flowchart](assets/reconnection_flow.svg)
-
-Like the connection flow the process starts over after a delay if the connection is closed or lost.
-The same exception for connection closed with 4003 applies as with the connection flow.
-Additionally after an invalidate message has been received and the connection flow fails, it should start over from the connection flow.
-
-
-### Server connection flow
-
-From the master server side new connections and reconnection attempts start out the same, a new connection has been made and the server sends the hello messoge to the client.
-If a vaild register\_\* message is received a new connection is set up for the client and the ready message is sent in reply.
-If a valid resume message is received and the session that's attempted to be resumed is active it'll signal that the session is resumed with a continue message and the client upon receiving the continue message should send the messages from its send buffer from after the last\_seq given in the continue message.
-
-If the session token used to resume is not valid it'll send an invalidate message and expect the client to continue with a registr\_\* message.
-If an invalid or unexpected message is received during the handshake the connection is closed.
-See the flowchart below.
-
-![Client connection flowchart](assets/server_flow.svg)
-
-For authentication failure the connection is closed with code 4003, which the connection client should interpret as connecting will never succeed and stop trying to reconnect.
-
-
-### Connection tracking and heartbeats
-
-Once connected as indicated by the ready and continue messages from the master server the client must start sending heartbeats at the interval given in the ready/continue message, and storing messages sent over the link in a sending side buffer.
-The heartbeats sent must have the seq of the last received message on the link and acts as an ack for received messages.
-The master server also sends heartbeats in the same manner and the client should remove messages up to and including the sequence number received in the heartbeat from its send buffer.
