+# Contribute guidelines
+
+We are always looking for people to help improve Impostor.
+
+## Code
+
+- If you are implementing or fixing an issue, please comment on the issue so work is not duplicated.
+- If you want to implementing a new feature, create an issue first describing the issue so we know about it. We are always open for discussion or questions on [Discord](https://discord.gg/Mk3w6Tb).
+- Don't commit unnecessary changes to the codebase or debugging code.
+- Write meaningful commits or squash them.
+- Please try to follow the code style of the rest of the codebase. An `.editorconfig` file has been provided to keep consistency.
+- Stylecop is also enabled: please make sure your PR compiles without warnings.
+
+## Pull requests
+
+- Only make pull requests to the `dev` branch.
+- Only implement one feature per pull request to keep it easy to understand.
+- Expect comments or questions on your pull request from the project maintainers. We try to keep the code as consistent and maintainable as possible.
+- Each pull request should come from a new branch in your fork, it should have a meaningful name.
+- We try to respond to pull requests as fast as possible. If you think we might have missed it, let us know on [Discord](https://discord.gg/Mk3w6Tb).
+
+If you have any questions, let us know.

 # Impostor
 
-Impostor is one of the first **Among Us** private servers, written in C#.
+[![Discord](https://img.shields.io/badge/Discord-chat-blue?style=flat-square)](https://discord.gg/Mk3w6Tb)
+[![CI](https://github.com/Impostor/Impostor/workflows/CI/badge.svg)](https://github.com/Impostor/Impostor/actions)
 
-The latest version supported is `2020.9.9`, both desktop and mobile.
+Impostor is the first working **Among Us** private server, written in C#.
 
-There are no special features at this moment, the goal is aiming to be as close as possible to the real server, for now. In a later stage, making modifications to game logic by modifying `GameData` can be looked at.
+As Among Us is actively updated, you may want to use the latest build from the master branch if you want to play on the latest version of Among Us that supported by Impostor.
 
-[Discord server for Impostor](https://discord.gg/Mk3w6Tb)
+If you want to play on an older version of Among Us, you can download old releases from [here](https://github.com/Impostor/Impostor/releases/), however these versions are less supported.
 
 ## Features
 
-Almost all standard features are implemented at this moment, except for public games. It is already possible to host and play private games.
-
-- [x] Create game
-- [x] Join game
-- [x] Start game
-- [ ] Find game
-- [x] V1 GameCodes (AAAA)
-- [x] V2 GameCodes (AAAAAA)
-- [x] Kick player
-- [x] Ban player
-- [ ] Server redirection
-- [ ] Server reselect
+- All Among Us features are implemented. It is a full replacement for the official server.
+- Plugin support.
+- Server-sided anticheat.
 
 ## Installation
 
-When hosting a server, make sure port **22023** is open and forwarded for **UDP**. It is not possible to use a different port because Among Us seems to have hardcoded 22023, even though the functionality for setting a port exists.

+# Building from source
+
+The solution contains the Impostor server and its dependencies, like Hazel and the plugin API. The server is built using [.NET 6](https://dotnet.microsoft.com/download/dotnet/6.0).
+
+## Cloning Impostor
+
+You need to clone Impostor using git:
+
+```bash
+git clone https://github.com/Impostor/Impostor.git
+```
+
+## Building the server
+
+### Dependencies
+
+- [.NET 6 SDK](https://dotnet.microsoft.com/download/dotnet/6.0)
+- [Rider](https://www.jetbrains.com/rider/) or [Visual Studio](https://visualstudio.microsoft.com/vs/) (Optional, only if you want the full IDE experience)
+
+### Build using the CLI
+
+```bash
+cd src/Impostor.Server/
+dotnet build
+# Or if you want a single file, ready for production: (change linux-x64 to win-x64 if you use Windows)
+dotnet publish -c Release -r linux-x64 -p:PublishSingleFile=true
+```
+
+To setup the server, please look at [Running the server](Running-the-server.md).

+# Frequently Answered Questions
+
+## What is this?
+
+The Impostor project is a reverse engineered and open source server for the game Among Us. The game itself is developed by [Innersloth](http://www.innersloth.com/) while this project is maintained by the community. This project was built out of frustration for the lack of server availability in certain regions and the inability for the core developer, [AeonLucid](https://github.com/AeonLucid), to join a public game. As of this time, it has not been officially endorsed by the studio.
+
+## Can this be used with the mobile version of the game?
+
+Yes, Impostor can be used with both the Android and iOS versions of the game. You can add a custom server via a link, you can do this using the [site](https://impostor.github.io/Impostor)
+
+## How can I get started?
+
+See [Setting up your Server](Running-the-server.md) for more information on running the server and [Client Setup](https://impostor.github.io/Impostor/) for helping your friends join in!
+
+If you're having issues with the server software, check the [Troubleshooting page](TROUBLESHOOTING.md).

+# Running the server
+
+There are currently two modes to run the Impostor server. The first way, Single Server, is the simplest one, can handle up to a few hundred simultaneous players, and is the one you should probably use. Multi-Server mode will distribute players across other servers and is intended for advanced users.
+
+## Single server
+
+### Without Docker
+
+1. Install the [.NET 6.0 runtime](https://dotnet.microsoft.com/download/dotnet/6.0). Installing the SDK also works, but is not necessary unless you plan on developing Impostor or Impostor plugins. If you're asked to pick between the normal, desktop or server runtime, the normal runtime is enough, but some plugins may require the ASP.NET Core Runtime as well.
+2. Find the [latest release](https://github.com/Impostor/Impostor/releases) or the [latest CI build](https://nightly.link/Impostor/Impostor/workflows/ci/master).
+3. Download the version for your OS (linux/win/osx). Impostor is built for multiple CPU-architectures, you most likely want the x64 version, unless you are running on a Raspberry Pi or another device with an ARM processor.
+4. Extract the zip.
+5. Modify `config.json` to your liking. Documentation can be found [here](Server-configuration.md) _(this step is mandatory if you want to expose this server to other devices)_
+6. Run `Impostor.Server` (Linux/macOS) or `Impostor.Server.exe` (Windows)
+
+Depending on your host you may also need to port forward Impostor to the internet. By default Impostor uses port **22023** and the **UDP** protocol. As port forwarding changes per host or router configuration, port forwarding is not covered by this guide.
+
+To connect to the server, you need to configure a region file on https://impostor.github.io/Impostor/
+
+### Using Docker
+
+[![Docker Image](https://img.shields.io/docker/v/aeonlucid/impostor?sort=semver)](https://hub.docker.com/r/aeonlucid/impostor)
+[![Docker Image](https://img.shields.io/docker/v/aeonlucid/impostor/nightly)](https://hub.docker.com/r/aeonlucid/impostor)
+
+After installing Docker, you can just start a Docker container with `docker run`:
+
+```
+docker run -p 22023:22023/udp aeonlucid/impostor:nightly
+```
+
+### Using Docker Compose
+
+```
+version: '3.4'
+
+services:
+  impostor:
+    image: aeonlucid/impostor:nightly
+    container_name: impostor
+    ports:
+      - 22023:22023/udp
+    volumes:
+      - /path/to/local/config.json:/app/config.json # For easy editing of the config
+      - /path/to/local/plugins:/app/plugins         # Only needed if using plugins
+      - /path/to/local/libraries:/app/libraries     # Only needed if using external libraries
+```
+
+## Multiple servers
+
+Follow the steps from the single server on two or more servers. You should only need to set this up if you have a very large server and can no longer fit everyone on one server: if this is your first time installing Impostor, use a single server.
+
+### Master server
+
+The master server will accept client connections and redirect them to the other servers listed in the configuration. It will not host any games itself.
+
+Example configuration:
+
+```json
+{
+  "Server": {
+    "PublicIp": "127.0.0.1",
+    "PublicPort": 22023,
+    "ListenIp": "0.0.0.0",
+    "ListenPort": 22023
+  },
+  "ServerRedirector": {
+    "Enabled": true,
+    "Master": true,
+    "Locator": {
+      "Redis": "",
+      "UdpMasterEndpoint": "127.0.0.1:22024"
+    },
+    "Nodes": [
+      {
+        "Ip": "127.0.0.1",
+        "Port": 22025
+      }
+    ]
+  }
+}
+```
+
+### Node servers
+
+The node server should have `ServerRedirector` enabled too, but `Master` **must be disabled**. Nodes do not need to be aware of each other.
+
+Example configuration:
+
+```json
+{
+  "Server": {
+    "PublicIp": "127.0.0.1",
+    "PublicPort": 22025,
+    "ListenIp": "0.0.0.0",
+    "ListenPort": 22025
+  },
+  "ServerRedirector": {
+    "Enabled": true,
+    "Master": false,
+    "Locator": {
+      "Redis": "",
+      "UdpMasterEndpoint": "127.0.0.1:22024"
+    }
+  }
+}
+```

+
+| Key            | Default     | Description                                                                                                                                                                                                                                                                                                                                                                                            |
+| -------------- | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| **PublicIp**   | `127.0.0.1` | This needs to the public IPv4 address of the server which you give to others to connect. You can find your IPv4 address [on this website](http://whatismyip.host/). Unless you are only planning to use Impostor privately, on your local network, you should change this to your public ip. It is also possible to use hostnames instead of IPv4 addresses, which will be resolved to IPv4 addresses. |
+| **PublicPort** | `22023`     | The public port of the server which you give to others to connect. (**This is the external port you configure on your router when port forwarding.**) Usually `22023`.                                                                                                                                                                                                                                 |
+| **ListenIp**   | `0.0.0.0`   | The network interface to listen on. If you do not know what to put here, use `0.0.0.0`. Since 1.2.2 it is also possible to use hostnames instead of IPv4 addresses, these must resolve to a valid IPv4 address.                                                                                                                                                                                        |
+| **ListenPort** | `22023`     | The listen port of the server, usually `22023`.                                                                                                                                                                                                                                                                                                                                                        |
+
+### AntiCheat
+
+Impostor has an Anticheat that makes it possible to kick cheaters from games automatically. Note that the anticheat is tuned on the vanilla version of the game, so client-side modifications could trigger the Anticheat if you're playing with them.
+
+| Key               | Default | Value                                                                                                                                                                                                               |
+| ----------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **Enabled**       | `true`  | Whether the anticheat should be enabled.                                                                                                                                                                            |
+| **BanIpFromGame** | `true`  | When anticheat is enabled and a player is caught hacking, they will be kicked from the server. If this value is set to `true`, the player will be banned instead and will not be able to rejoin that specific game. |
+
+### Compatibility
+
+Impostor has two compatibility options which allow some extra flexibility but may not work properly. Enabling either of these options is not recommended.
+
+| Key                      | Default | Value                                                                                                                                                                          |
+| ------------------------ | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| **AllowNewGameVersions** | `false` | Warning: Setting this option to `true` is unsupported and may cause issues when large updates to Among Us are released. Allow future versions of Among Us to join your server. |
+| **AllowVersionMixing**   | `false` | Allow players using different game versions to play in one lobby.                                                                                                              |
+
+### Debug
+
+The Debug configuration is used to enable the game recorder. This is mostly useful when developing Impostor.

+| Key                     | Default | Value                                        |
+| ----------------------- | ------- | -------------------------------------------- |
+| **GameRecorderEnabled** | `false` | Enables the Game Recorder.                   |
+| **GameRecorderPath**    | _empty_ | Path where the recorded games will be saved. |
+
+### ServerRedirector
+
+In a multi-node setup these values need to be specified. Note that most people do not need to run a Multi-node setup.
+
+| Key                    | Default | Value                                                                                                                                             |
+| ---------------------- | ------- | ------------------------------------------------------------------------------------------------------------------------------------------------- |
+| **Enabled**            | `false` | Whether the server runs in multi-node setup. If this is `false`, all other options in this section do not have any effect.                        |
+| **Master**             | `false` | Whether the current server is a master. A master is responsible for redirecting clients to nodes                                                  |
+| **Locator**            |         | Fill in either `Redis` or `UdpMasterEndpoint` to choose which method to use for locating other nodes. This must be the same across all servers.   |
+| **>Redis**             |         | Format `127.0.0.1.6379`, you can also use a password like so: `127.0.0.1.6379,password=value`.                                                    |
+| **>UdpMasterEndpoint** |         | On the master, this value acts as a listen ip and port. On a node, this should be the public ip and port of the master. Format `127.0.0.1:32320`. |
+| **Nodes**              |         | An array containing public ips and ports of nodes. Only needs to be set on the master. See above for an example.                                  |
+
+### Serilog (Logging)
+
+Impostor's log framework, Serilog, can be configured in the config file. You can change its default log level and you can add additional sinks.
+
+| Key              | Default       | Value                                                                                                                                                                                                                          |
+| ---------------- | ------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ |
+| **MinimumLevel** | `Information` | Minimum log level for a message to be printed. If a log entry is as severe or more severe than this level, it will be printed. From most severe to least severe: `Fatal`,`Error`, `Warning`, `Information`, `Debug`, `Verbose` |
+| **Using**        | `[]`          | List of additional Serilog Sinks assemblies to load.                                                                                                                                                                           |
+| **WriteTo**      | `[]`          | Additional logging sinks. See the Serilog documentation or the example in this section. Serilog                                                                                                                                |
+
+For more information, check the [Serilog.Settings.Configuration](https://github.com/serilog/serilog-settings-configuration) documentation.
+
+For example, to add logging to a file, you should add the following snippet to your configuration:
+
+```json
+"Serilog": {
+  "Using": [
+    "Serilog.Sinks.File"
+  ],
+  "WriteTo": [
+    {
+      "Name": "File",
+      "Args": {
+        "path": "logs/log.txt",
+        "rollingInterval": "Day"
+      }
+    }
+  ]
+}
+```
+
+Next to that, you also need to copy over Serilog.Sinks.File.dll from [NuGet](https://www.nuget.org/packages/Serilog.Sinks.File/). See the [Serilog.Sinks.File documentation](https://github.com/serilog/serilog-sinks-file#json-appsettingsjson-configuration) for a list of parameters that can be configured.
+
+Other Serilog sinks are also supported, but are out of scope for this documentation.
+
+## Config providers
+
+### File
+
+The simplest option to configure is by using the `config.json` file next to the server executable. For all possible options see the [config-full.json](https://github.com/Impostor/Impostor/blob/dev/src/Impostor.Server/config-full.json) file.
+
+### Environment variables
+
+If you're unable to edit the config.json file, you can instead set Environment variables to configure Impostor. The general pattern for each variable is `IMPOSTOR_SectionName__VariableName`. For example, to disable the anticheat, you can set the environment variable `IMPOSTOR_AntiCheat__Enabled=false`. Here are some more examples:
+
+```
+IMPOSTOR_Server__PublicIp=127.0.0.1
+IMPOSTOR_Server__PublicPort=22023
+IMPOSTOR_Server__ListenIp=0.0.0.0
+IMPOSTOR_Server__ListenPort=22023
+IMPOSTOR_AntiCheat__Enabled=true
+IMPOSTOR_AntiCheat__BanIpFromGame=true
+IMPOSTOR_ServerRedirector__Enabled=false
+IMPOSTOR_ServerRedirector__Master=true
+IMPOSTOR_ServerRedirector__Locator__Redis=127.0.0.1.6379
+IMPOSTOR_ServerRedirector__Locator__UdpMasterEndpoint=127.0.0.1:32320
+IMPOSTOR_ServerRedirector__Nodes__0__Ip=127.0.0.1
+IMPOSTOR_ServerRedirector__Nodes__0__Port=22024
+IMPOSTOR_ServerRedirector__Nodes__1__Ip=127.0.0.1
+IMPOSTOR_ServerRedirector__Nodes__1__Port=22025
+```

+# Troubleshooting
+
+If you're reading this, something went wrong.
+Don't worry though, as this is the most thorough guide to help you!
+
+## `./Impostor.Server: line 1: ELF: not found` (plus other errors)
+
+No idea where you got that system. But we clearly do **NOT** support it.
+
+## `cannot execute binary file: Exec format error`
+
+Please check that you have downloaded the right version of Impostor, as we mantain two CPU architectures (x64 and ARM).
+Unless you are running Impostor on a computer like the Raspberry Pi, you most likely want to use the x64 version.
+
+## `./Impostor.Server: Permission denied`
+
+This is an error related to Linux file permissions.
+Some files do not hold their executable bit (the permission that allows them to run) during a download.
+You can solve this by doing: `chmod +x Impostor.Server`
+
+## Disconnected with `Your client is too new, please update your Impostor to play`
+
+This happens when your game is too new for your copy of Impostor to support.
+
+If you're using an Impostor release, check if there is a newer release available that supports your version. If this doesn't exist, you can try the [latest build from CI](https://nightly.link/Impostor/Impostor/workflows/ci/master).
+
+If even that build doesn't work, you can try looking through the Pull Requests to see if there is a pending pull request that aims to update it to the next version, but note these may be unstable and may contain malicious code, as they haven't been vetted by the Impostor development team yet.
+
+## Disconnected with `Please update your game to play on this server`
+
+This happens when you're using a version of Impostor that is too new for your game version. You can download an older version from [the GitHub release page](https://github.com/Impostor/Impostor/releases). We however don't support older versions of Impostor with new API's and bugfixes so we recommend to update your game instead.
+
+## Disconnected with `You are using an older version of the game`
+
+You are using a version of Impostor that is not designed for the version of the game you're playing. The game does not really check who is outdated and blames it on the user. Newer versions (v1.5.0+) do warn correctly and send the correct message.
+
+Look at which version of the game you're playing, which you can see in the top left corner of the main menu, then download an Impostor version for that game. Every [release on the release page](https://github.com/Impostor/Impostor/releases) shows which version of the game it is compatible with. If your game version is newer than the latest release, check if the [latest build from CI works](https://nightly.link/Impostor/Impostor/workflows/ci/master).
+
+## Disconnected with `You disconnected from the server. Reliable Packet 1 ...`
+
+Please double-check that you have followed the [Server Configuration](Server-configuration.md) correctly.
+**NOTE: Your public ip does not start with `10`, `127` or `192`**
+Also check if the port Impostor (ListenPort) is listening on is correctly port-forwarded for UDP (or TCP/UDP).
+
+## `Could not load file or assembly...`
+
+Please check that you only have **working** plugins in the `plugins` folder.
+This error can be caused by non-plugin files or plugins that are not working correctly.
+
+## My question is not yet answered and I'm still having problems!
+
+That's unfortunate. Join the [Impostor Discord](https://discord.gg/Mk3w6Tb), ask your question there and we'll try to help you out. Note that we're not always available, so it may take some time to get an answer. To make answering your question easier, please add the following details:
+
+- Which version of Impostor are you using?
+- Which version or Among Us are you using?
+- Which operating system are you running Impostor on?
+- If you have console logs, attaching these will also help.

+
+## 1. Install .NET SDK
+
+Download and install the latest .NET SDK.
+
+https://dotnet.microsoft.com/download
+
+## 2. Create a C# project
+
+The first step is creating a new C# project, it must be a **Class Library (.NET Standard)**. The target framework can be any of those compatible with .NET 6, which includes:
+
+- .NET Standard 2.0
+- .NET Standard 2.1
+- .NET 5
+- .NET 6
+
+For more information about compatibility, see https://docs.microsoft.com/en-us/dotnet/standard/net-standard.
+
+> At the moment of writing this document, I recommend you to use **.NET Standard 2.1**. This should give you enough functionality. If not, upgrade to .NET 6.
+
+When the project has been created, you should have `Class.cs` and `Project.csproj` files. Your `Project.csproj` should look something like this.
+
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+    <PropertyGroup>
+        <TargetFramework>netstandard2.1</TargetFramework>
+    </PropertyGroup>
+</Project>
+```
+
+## 3. Add the Impostor.Api library
+
+You only have to follow the instructions of one below. 
+
+### Quick
+
+Install the `Impostor.Api` NuGet package.  
+Make sure to get a prerelease if you are writing a plugin for a dev release of the server.
+
+### Visual Studio
+
+1. Right click your project.
+2. Click `Manage NuGet Packages`.
+3. Click `Browse`.
+4. Search for `Impostor.Api`.
+5. Click the `Impostor.Api` result and press install on the right side.
+
+### Dotnet CLI
+
+1. Open your project folder in command prompt / bash.
+2. Run `dotnet add package Impostor.Api`.
+
+## 4. The plugin class
+
+Now the `Impostor.Api` is installed, you need to create a class for your plugin. A plugin **must** contain exactly one. See the code below for an example.
+
+```csharp
+using System.Threading.Tasks;
+using Impostor.Api.Events.Managers;
+using Impostor.Api.Plugins;
+using Microsoft.Extensions.Logging;
+
+namespace Impostor.Plugins.Example
+{
+    /// <summary>
+    ///     The metadata information of your plugin, this is required.
+    /// </summary>
+    [ImpostorPlugin(
+        package: "gg.impostor.example",
+        name: "Example",
+        author: "AeonLucid",
+        version: "1.0.0")]
+    public class ExamplePlugin : PluginBase // This is also required ": PluginBase".
+    {
+        /// <summary>
+        ///     A logger that works seamlessly with the server.
+        /// </summary>
+        private readonly ILogger<ExamplePlugin> _logger;
+
+        /// <summary>
+        ///     The constructor of the plugin. There are a few parameters you can add here and they
+        ///     will be injected automatically by the server, two examples are used here.
+        ///
+        ///     They are not necessary but very recommended.
+        /// </summary>
+        /// <param name="logger">
+        ///     A logger to write messages in the console.
+        /// </param>
+        /// <param name="eventManager">
+        ///     An event manager to register event listeners.
+        ///     Useful if you want your plugin to interact with the game.
+        /// </param>
+        public ExamplePlugin(ILogger<ExamplePlugin> logger, IEventManager eventManager)
+        {
+            _logger = logger;
+        }
+
+        /// <summary>
+        ///     This is called when your plugin is enabled by the server.
+        /// </summary>
+        /// <returns></returns>
+        public override ValueTask EnableAsync()
+        {
+            _logger.LogInformation("Example is being enabled.");
+            return default;
+        }
+
+        /// <summary>
+        ///     This is called when your plugin is disabled by the server.
+        ///     Most likely because it is shutting down, this is the place to clean up any managed resources.
+        /// </summary>
+        /// <returns></returns>
+        public override ValueTask DisableAsync()
+        {
+            _logger.LogInformation("Example is being disabled.");
+            return default;
+        }
+    }
+}
+```
+
+## 5. Adding an event listener
+
+Currently you should have a plugin that loads and does nothing. In order to get some actual functionality, you need to add an event listener.
+
+Create a new class called `GameEventListener`. Example code:
+
+```csharp
+using Impostor.Api.Events;
+using Impostor.Api.Events.Player;
+using Microsoft.Extensions.Logging;
+
+namespace Impostor.Plugins.Example.Handlers
+{
+    /// <summary>
+    ///     A class that listens for two events.
+    ///     It may be more but this is just an example.
+    ///
+    ///     Make sure your class implements <see cref="IEventListener"/>.
+    /// </summary>
+    public class GameEventListener : IEventListener
+    {
+        private readonly ILogger<ExamplePlugin> _logger;
+
+        public GameEventListener(ILogger<ExamplePlugin> logger)
+        {
+            _logger = logger;
+        }
+
+        /// <summary>
+        ///     An example event listener.
+        /// </summary>
+        /// <param name="e">
+        ///     The event you want to listen for.
+        /// </param>
+        [EventListener]
+        public void OnGameStarted(IGameStartedEvent e)
+        {
+            _logger.LogInformation($"Game is starting.");
+
+            // This prints out for all players if they are impostor or crewmate.
+            foreach (var player in e.Game.Players)
+            {
+                var info = player.Character.PlayerInfo;
+                var isImpostor = info.IsImpostor;
+                if (isImpostor)
+                {
+                    _logger.LogInformation($"- {info.PlayerName} is an impostor.");
+                }
+                else
+                {
+                    _logger.LogInformation($"- {info.PlayerName} is a crewmate.");
+                }
+            }
+        }
+
+        [EventListener]
+        public void OnGameEnded(IGameEndedEvent e)
+        {
+            _logger.LogInformation($"Game has ended.");
+        }
+
+        [EventListener]
+        public void OnPlayerChat(IPlayerChatEvent e)
+        {
+            _logger.LogInformation($"{e.PlayerControl.PlayerInfo.PlayerName} said {e.Message}");
+        }
+    }
+}
+```
+
+## 6. Registering the event listener
+
+The last step to get your plugin working is to register the event listener, so the server knows about it. Go back to your plugin class and modify it as below.
+
+```csharp
+using System;
+using System.Threading.Tasks;
+using Impostor.Api.Events.Managers;
+using Impostor.Api.Plugins;
+using Impostor.Plugins.Example.Handlers;
+using Microsoft.Extensions.Logging;
+
+namespace Impostor.Plugins.Example
+{
+    [ImpostorPlugin(
+        package: "gg.impostor.example",
+        name: "Example",
+        author: "AeonLucid",
+        version: "1.0.0")]
+    public class ExamplePlugin : PluginBase
+    {
+        private readonly ILogger<ExamplePlugin> _logger;
+        // Add the line below!
+        private readonly IEventManager _eventManager;
+        // Add the line below!
+        private IDisposable _unregister;
+
+        public ExamplePlugin(ILogger<ExamplePlugin> logger, IEventManager eventManager)
+        {
+            _logger = logger;
+            // Add the line below!
+            _eventManager = eventManager;
+        }
+
+        public override ValueTask EnableAsync()
+        {
+            _logger.LogInformation("Example is being enabled.");
+            // Add the line below!
+            _unregister = _eventManager.RegisterListener(new GameEventListener(_logger));
+            return default;
+        }
+
+        public override ValueTask DisableAsync()
+        {
+            _logger.LogInformation("Example is being disabled.");
+            // Add the line below!
+            _unregister.Dispose();
+            return default;
+        }
+    }
+}
+
+```
+
+## 7. Build and run your plugin
+
+Now your plugin is ready to be tested.
+
+1. Right click your project and press `Build`.
+2. Right click your project and press `Open Folder in File Explorer`.
+3. Go to `bin/Debug/netstandard2.1/`.
+4. In this directory, you should find your plugin named `Project.dll`.
+5. Copy the `Project.dll` to the `plugins` directory in your Impostor server directory.
+6. (Re)start your Impostor server.
+7. Open Among Us, create a game and send a chat message. In the console you should see your plugin being loaded and the messages from the example.
+
+## 8. Extra
+
+Some extra information that might be useful for those developing plugins.
+
+### Event listeners
+
+- You can have multiple event listener on the same event.
+- An event listener can be given a priority `[EventListener(EventPriority.Normal)]` and is called in order.
+- It is not recommended to block for a long time inside `EventListener` because the events are called from inside the packet handlers. Blocking too long causes the client to time out. You should create a new `Task` for operations that will take a lot of time. 
+
+### Dependency injection
+
+- The main plugin class is constructed by the `IServiceProvider` of the server and can inject everything the server uses. A few examples are:
+  - `ILogger<T>`
+  - `IEventManager`
+  - `IClientManager`
+  - `IOptions<ServerConfig>`
+  - `IOptions<ServerRedirectorConfig>`
+- You can add your own classes and `EventListener` implementation to the `IServiceProvider` by creating a new class and implementing `IPluginStartup`. Make sure to register them as a singleton `services.AddSingleton<IEventListener, GameEventListener>();`.
+
+### Server configuration
+
+Constantly copying the plugin dll to your server directory can be pretty annoying. Luckily we have a solution for that. In your Impostor server open the `config.json` and add the `PluginLoader` from the example below, replace the path with the build destination of your plugin.
+
+```json
+{
+  "Server": {
+    "PublicIp": "127.0.0.1",
+    "PublicPort": 22023,
+    "ListenIp": "0.0.0.0",
+    "ListenPort": 22023
+  },
+  "PluginLoader": {
+    "Paths": [
+      "D:\\Projects\\Impostor\\src\\Impostor.Plugins.Example\\bin\\Debug\\netstandard2.1"
+    ],
+    "LibraryPaths": []
+  }
+}
+```
+
+### Using other libraries
+
+Sometimes you need to use libraries that the original Impostor server does not provide. The dll files of these libraries must be placed in the `libraries` folder next to the server executable. You could also provide them by modifying the `PluginLoader.LibraryPaths` option in the `config.json`, similarly to the `PluginLoader.Paths` option.
+
+### Impostor versions
+
+It is important to use the correct versions when working with `Impostor.Api` prereleases and the `Impostor` dev builds to reduce the chances of mismatching assemblies. 
+
+**Example** 
+
+The prerelease `Impostor.Api` package `1.2.0-ci.54` belongs to build `54` on AppVeyor, which can be found here https://ci.appveyor.com/project/Impostor/Impostor/build/54. Notice the `54` on the end of the url.
+
+## 9. Missing/invalid data or want more functions?
+
+The `Impostor.Api` is currently in beta. There are a lot of things still missing and we would like to hear from you what you need to develop a plugin.
+
+Create an issue:
+
+- [Suggest a function](https://github.com/Impostor/Impostor/issues/new?template=3--api-suggestion.md)
+- [Data is invalid](https://github.com/Impostor/Impostor/issues/new?template=4--api-invalid.md)
+- [Data is unavailable](https://github.com/Impostor/Impostor/issues/new?template=5--api-missing.md)
