+# 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.

+[![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 8](https://dotnet.microsoft.com/download/dotnet/8.0).
+
+## Cloning Impostor
+
+You need to clone Impostor using git:
+
+```bash
+git clone https://github.com/Impostor/Impostor.git
+```
+
+## Building the server
+
+### Dependencies
+
+- [.NET 8 SDK](https://dotnet.microsoft.com/download/dotnet/8.0)
+- [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).

docs/Http-server.md

+# HTTP Server
+
+Since Impostor 1.9.0 a HTTP service is included for matchmaking. Recent versions of Among Us require this service in order to connect correctly and not kick players after a round.
+
+Depending on whether you want to support mobile players, you can set up the HTTP server in one of two ways:
+
+- Directly expose the HTTP server. Simpler, but only works if you don't want to support mobile players.
+- Use a reverse proxy to expose the HTTP server. More complex, but allows mobile players to connect.
+
+## Directly expose the HTTP server.
+
+In config.json, set "ListenIp" to "0.0.0.0" in the "HttpServer" section. If you don't have this section, look in the example [config.json](https://github.com/Impostor/Impostor/blob/master/src/Impostor.Server/config.json)
+
+## Use a reverse proxy
+
+A reverse proxy allows you to forward HTTP requests from users to multiple services. If you already have one, you should configure it to add Impostor. This page contains an Nginx configuration you can use for reference.
+
+If you have never set up a reverse proxy before, we recommend you to set up [Caddy](https://caddyserver.com/). It is easy to set up and comes with support for requesting SSL certificates out of the box.
+
+To prevent people from connecting directly to Impostor, we recommend changing the "ListenIp" in the "HttpServer" section to "127.0.0.1". This makes sure people can't connect to your HTTP server other than via your reverse proxy. Keep the "ListenIp" in the "Server" section at "0.0.0.0" though, running the normal game traffic through a proxy is not supported.
+
+### Caddy
+
+To install Caddy, follow the [official installation guide](https://caddyserver.com/docs/install). Then use the following lines as your `Caddyfile` configuration file:
+
+```
+example.com # replace example.com with your domain name
+
+reverse_proxy :22023
+```
+
+Now run `caddy run` in the folder with this Caddyfile and it should set up a server for you with a free SSL certificate.
+If this works, you should set up [Caddy to run in the background](https://caddyserver.com/docs/running)
+
+### Nginx
+
+Nginx is an alternative to Caddy that is a bit harder to set up. If you already use Nginx, you can use our snippet to add Impostor:
+
+<details><summary>Nginx configuration</summary>
+
+```nginx
+server {
+    listen 443 ssl http2;
+    server_name example.com; # replace example.com with your domain name
+
+    # Assuming you're using Certbot, replace example.com with your domain name
+    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
+    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
+    ssl_trusted_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
+
+    location / {
+        proxy_pass http://localhost:22023; # Change the port to your HttpServer's ListenPort
+        proxy_set_header X-Forwarded-For $remote_addr;
+        proxy_set_header X-Forwarded-Proto $scheme;
+    }
+}
+
+# Redirect all traffic to HTTPS
+server {
+    listen 80 default_server;
+    location / {
+        return 307 https://$host$request_uri;
+    }

+# Running the server
+
+There are currently two install methods for Impostor: You can install it normally or inside of a Docker container. If you do not have a particular preference, we recommend the normal installation over the Docker container method.
+
+## General remarks for both install methods
+
+This section applies to both the normal installation as well as the Docker (Compose) installation
+
+To connect to the server, you need to configure and install a region file on https://impostor.github.io/Impostor/
+
+Among Us connects to the server using two network services: the (TCP) HTTP service points Among Us to the UDP service, then the UDP service hosts the actual game traffic. Because of this, Impostor uses port 22023 using **both** the TCP and UDP protocols.
+
+As the phone version of Among Us requires this HTTP connection to be secure, we recommend using a HTTP reverse proxy to terminate SSL on the HTTP service. Setup instructions for this are in the [Http Server documentation](Http-server.md).
+
+Depending on your host you may also need to port forward Impostor to the internet or pass Impostor traffic by your firewall. Port 22023 UDP needs to be accessible for everyone that wants to play on the server, then you also need to portforward your HTTP reverse proxy or port 22023 TCP if you don't use a reverse proxy. As port forwarding changes per host or router configuration, port forwarding is not covered by this guide.
+
+## Normal installation
+
+1. Install [.NET 8.0](https://dotnet.microsoft.com/download/dotnet/8.0). We recommend either the ASP.NET Core Runtime or the SDK. The SDK is necessary in case you want to develop Impostor or Impostor plugins.
+2. Download the [latest release](https://github.com/Impostor/Impostor/releases) or the [latest CI build](https://nightly.link/Impostor/Impostor/workflows/ci/master). Note that Impostor is built for multiple CPU-architectures and operating systems, you most likely want the x64 version, unless you are running on a Raspberry Pi or another device/VPS with an Arm processor.
+3. Extract the zip.
+4. Modify `config.json` to your liking. Documentation can be found [here](Server-configuration.md). You need to at least change `PublicIp` to the address people will connect to your server to.
+5. Run `Impostor.Server` (Linux/macOS) or `Impostor.Server.exe` (Windows)
+6. (OPTIONAL - Linux) Configure a systemd definition file and enable the service to start on boot, see [systemd configuration](Server-configuration.md#systemd)
+7. (OPTIONAL) Set up a reverse proxy to support HTTPS, so mobile phones can connect, see [reverse proxy configuration](Http-server.md)
+
+## 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)
+
+Docker is a program that allows you to run programs like Impostor in a container.
+
+After installing Docker, you can just start a Docker container with `docker run`:
+
+```
+docker run -p 22023:22023/tcp -p 22023:22023/udp -e IMPOSTOR_Server__PublicIp=your.public.ip.here aeonlucid/impostor:nightly
+```
+
+Please replace `your.public.ip.here` with the public IP address of your server. This is the address Among Us will try to reach your server at.
+
+To configure the docker container, either use environment variables or mount config.json in your container.
+
+## Using Docker Compose
+
+Docker Compose allows you to start a Docker container using a prefined configuration. This is an example configuration you can continue on:
+
+```
+version: '3.4'
+
+services:
+  impostor:
+    image: aeonlucid/impostor:nightly
+    container_name: impostor
+    ports:
+      - 22023:22023/tcp # Add "127.0.0.1:" if you're using a reverse proxy to terminate HTTPS
+      - 22023:22023/udp
+    environment: # Either configure Impostor using environment variables or mount a copy of config.json
+      - IMPOSTOR_Server__PublicIp=your.public.ip.here
+    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

+| **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.                                                                                                                                                                                        |

For port forwarding purposes: this is an UDP port                                                                                                                                                                                                                                                                                                                                                       |
+
+### HttpServer
+
+Impostor has an Http Server that is used by recent versions of Among Us to connect to. See [the Http Server page](Http-server.md) for more details on how to set this up.
+
+| Key            | Default   | Description                                                                                                                                                                |
+|----------------|-----------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
+| **Enabled**    | `true`    | Whether the http server should be enabled.                                                                                                                                 |
+| **ListenIp**   | `0.0.0.0` | The network interface to listen on. Use `127.0.0.1` if you use a reverse proxy or just run locally. Use `0.0.0.0` if you are directly exposing this server to the internet |
+| **ListenPort** | `22023`   | The listen port of this server. For port forwarding purposes, this is an TCP port.                                                                                         |
+
+### 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. |
+| **AllowCheatingHosts**     | `"Never"` | Configure whether hosts are allowed to cheat. "Never" forbids it, "Always" allows it. "IfRequested" allows hosts to cheat if they connect with the DisableServerAuthorityFlag set.                                  |
+| **EnableGameFlowChecks**   | `true`    | Enable checks that check if certain actions are done in the appropriate order or at the appropriate moment in the game. This includes changing cosmetics while in game or murdering too fast.                       |
+| **EnableMustBeHostChecks** | `true`    | Enables checks that check if players are the host before they can do actions that require them to be host of the game. This includes starting the game and spawning objects.                                        |
+| **EnableColorLimitChecks** | `true`    | Enables checks that checks if players request colors that are already in use.                                                                                                                                       |
+| **EnableNameLimitChecks**  | `true`    | Enables checks that checks if player names have a length that is possible to set using the user interface.                                                                                                          |
+| **EnableOwnershipChecks**  | `true`    | Enables checks that check if players are allowed to perform a certain action on themself or another player.                                                                                                         |
+| **EnableRoleChecks**       | `true`    | Enables checks that check if players have the correct role when performing certain role abilities like venting or murdering.                                                                                        |
+| **EnableTargetChecks**     | `true`    | Enables checks that check if certain packets to everyone that should only have been sent to certain players or vice versa. This includes sending votes or network objects.                                          |
+
+| **ForbidProtocolExtensions** | `true`  | If disabled allows players to send network packets that go beyond the network packets sent by the vanilla game. This is necessary for most mods that need all players to install it.                                |
+
+### 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. |
+
+### 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
+```
+
+# systemd
+
+Linux users will likely want to create a systemd service definition to manage running the Impostor application.  Benefits to using a systemd service include the following:
+
+- The server process can automatically restart if the process dies
+- Impostor can be set to start on boot (handy if you do system updates regularly)
+- You can use systemd targets to ensure the process doesn't start until the system dependencies are met
+
+Using your favorite text editor, create the following service file:
+
+```
+sudoedit /etc/systemd/system/impostor.service
+```
+
+Modify the following template to your needs and populate the service file.
+
+```
+[Unit]
+Description=Impostor private Among Us server - https://github.com/Impostor/Impostor
+
+[Service]
+# Directory where Impostor is installed
+WorkingDirectory=/opt/impostor
+# Path to Impostor binary
+ExecStart=/opt/impostor/Impostor.Server
+Restart=always
+# Restart service after 10 seconds if the dotnet service crashes
+RestartSec=10
+KillSignal=SIGTERM
+SyslogIdentifier=impostor
+
+# User and group that will run the Impostor server process -- ensure that user is allowed to execute the binary
+User=impostor
+Group=impostor
+TimeoutStopSec=10
+
+[Install]
+# Wait until most system services have started before starting Impostor
+After=multi-user.target
+WantedBy=multi-user.target
+```
+
+Reload all systemd unit files to source in the new file you've created.
+
+```
+sudo systemctl daemon-reload
+```
+
+Start the service. 
+
+```
+sudo systemctl start impostor.service
+```
+
+Check the log for the service and verify it has started correctly -- Hint: Use the Q key to quit out of journalctl.
+
+```
+sudo journalctl -u impostor.service
+```
+
+If everything has started correctly, ensure the service is set to start on boot.
+
+```
+sudo systemctl enable impostor.service
+```

+# 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.

+# Upgrading Impostor
+
+Sometimes we make incompatible changes to existing code. This document lists these changes and which changes you should make as a server administrator.
+
+## Impostor 1.9.0
+
+Previously we recommended using the Impostor.Http plugin for HTTP matchmaking. Because Among Us now relies on HTTP matchmaking, this plugin is now part of the default installation. As a result, you should change your server as follows:
+
+- If you have Impostor.Http installed, you should remove that plugin. If you have changed the default settings, you need to move these changes to the [HttpServer section in config.json](Server-configuration.md#HttpServer).
+- If you have plugins that required Impostor.Http's API (like Reactor.Impostor.Http), you should check that plugin for updates
+- It is no longer necessary to add the ASP.NET Core folder to the PluginLoader's LibraryPaths

+
+## 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 8, but we recommend sticking with **.NET 8.0**.
+
+For more information about compatibility, see https://docs.microsoft.com/en-us/dotnet/standard/net-standard.
+
+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>net8.0</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.

+}
+```
+
+## 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/net8.0/`.
+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>`
+- 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\\net8.0"
+    ],
+    "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)
+- [Other](https://github.com/Impostor/Impostor/issues/new?template=6--api-other.md)
