+## [4.2.0] - 14.06.2022
+
+### Added
+
+- Added `data/searches.yml` file which configures some of the new search functionality
+  The file comments explaining what each property does.
+  Explained briefly here:
+  ```yml
+  # what will be used for .google command. Either google (official api) or searx
+  webSearchEngine: Google
+  # what will be used for .img command. Either google (official api) or searx
+  imgSearchEngine: Google
+  # how will yt results be retrieved: ytdataapi or ytdl or ytdlp
+  ytProvider: YtDataApiv3
+  # in case web or img search is set to searx, the following instances will be used:
+  searxInstances: []
+  # in case ytProvider is set to invidious, the following instances will be used
+  invidiousInstances: []
+  ```
+- Added new properties to `creds.yml`. google -> searchId and google -> searchImageId.
+- These properties are used as `cx` (google api query parameter) in case you've setup your `data/searches.yml` to use the official google api.
+  `searchId` is used for web search
+  `searchimageId` is used for image search
+  ```yml
+  google:
+      searchId: ""
+      searchImageId: ""
+  ```
+- Check `creds_example.yml` for comments explaining how to obtain them.
+
+#### Patronage system added
+- Added `data/patron.yml` for configuration
+- Implemented only for patreon so far
+- Patreon subscription code completely rewritten
+- Users who pledge on patreon get benefits based on the amount they pledged
+- Public nadeko only. But selfhosters can adapt it to their own patreon pages by configuring their patreon credentials in `creds.yml` and enabling the system in `data/patron.yml` file.
+  - Most of the patronage system strings are hardcoded atm, so if you wish to use this system on selfhosts, you will have to modify the source
+- Pledge amounts are split into tiers. This is not configurable atm.
+  - Tier I - 1$ - 4.99$ a month
+  - Tier V - 5$ - 9.99$ a month
+  - Tier X - 10$ - 19.99$ a month
+  - Tier XX - 20$ - 49.99$ a month
+  - Tier L - 50$ - 99.99$ a month
+  - Tier C - 100$+ a month
+- Rewards and command quotas for each of the tiers are configurable
+- Limitations to certain features are also configurable. ex:
+```yml
+quotas:
+    features:
+        "rero:max_count":
+            x: 50
+```
+- ^ this setting would set the maximum number of reaction roles to be 50 for a user who is in Patron Tier X
+- Read the comments in the .yml file for (much) more info
+- Quota system allows the owner to set up hourly, daily and monthly quota usage for each tier
+- Quota system applies to entire server owner by a patron
+  - Patron spends own quota by using the commands on any server
+  - Any user on *any* server owned by a patron spends that patron's quota
+- When users subscribe to patreon they will receive a welcome message
+  - If you're enabling patron system for a selfhost, you will want to edit it
+
+Added `.patron` and `.patronmessage` commands
+- `.patron` checks your patronage status, and quotas. Requires patron system to be enabled.
+- `.patronmessage` (owner only) sends message to all patrons with the specified tier or higher. Supports embeds
+
+- Added a fake `.cmdcd` command `cleverbot:response` which can be used to limit how often users can talk to the cleverbot.
+
+### Changed
+
+- CurrencyReward now support adding additional flowers to patrons.
+- `.donate` command completely reworked.
+  - Works only on public bot (OnlyPublicBotAttribute)
+  - Guides user on how to donate to support the project
+  - Added interaction explaining selfhosting
+
+- `.google` reimplemented. It now has 2 modes configurable in `data/searches.yml` under the `webSearchengine` property
+  - If set to `google`, official custom search api will be used. You will need to set googleapikey and google.searchId in `creds.yml`
+  - if set to `searx` one of the instances specified in the `searxInstances:` property will be randomly chosen for each request
+    - instances must have `format=json` allowed (public ones usually don't allow it)
+    - instances are specified as a fully qualified url, example: `https://my.cool.searx.instance.io`
+- `.image` reimplemented. Same as `.google` - it uses either `google` official api (in which case it uses `google.searchImageId` from `creds.yml`) or `searx`
+
+- `.youtube` reimplemented. It will use a `ytProvider:` property from `data/searches.yml` to determine how to retrieve results
+  - `ytdataapi` will use the official google api (requires `GoogleApiKey` specified in `creds.yml`) and YoutubeDataApi enabled in the dev console
+  - `ytdl` will use `youtube-dl` program from the host machine. It must be downloaded and it's location must be added to path env variable.
+  - `ytdlp` will use `yt-dlp` program from the host machine. Same as `youtube-dl` - must be in path env variable.
+  - `invidious` will use one of invidious instances specified in the `invidiousInstances` property. Very good. 
+
+- `.google`, `.youtube` and `.image` moved to the new Search group
+
+Note: Results of each `.youtube` query will be cached for 1 hour to improve perfomance
+- Removed 30 second `.ping` ratelimit on public nadeko
+
+- xp image generation changes
+  - In case you have default settings, your xp image will look slightly different
+  - If you've modified xp_template.json, your xp image might look broken. Your old template will be saved in xp_template.json.old
+  - Xp number outline is now slightly thicker
+  - Xp number will now have Center vertical and horizontal alignment
+  - LastLevelUp no longer supported
+
+- Some commands will now use timestamp tags for better user experience
+- `.prune` was slightly slowed down to avoid ratelimits
+- `.wof` moved from it's own group to the default Gambling group
+- `.feed` urls which error for more than 100 times will be automatically removed.
+- `.ve` is now enabled by default
+
+- [dev] nadeko interaction slightly improved to make it less nonsense (they still don't make sense)  
+- [dev] RewardedUsers table slightly changed to make it more general  
+- [dev] renamed `// todo`s which aren't planned soon to `// FUTURE`  
+- [dev] currency rewards have been reimplemented and moved to a separate service  
+
+### Fixed
+ 
+- `.rh` no longer needs quotes for multi word roles
+- `.deletexp` will now properly delete server xp too
+- Fixed `.crypto` sparklines
+- [dev] added support for configs to properly parse enums without case sensitivity (ConfigParsers.InsensitiveEnum)
+- [dev] Fixed a bug in .gencmdlist  
+- [dev] small fixes to creds provider  
+

+  - Website to create them is live at eb.nadeko.bot (old one is moved to oldeb.nadeko.bot)
+  - Embed arrays don't have a plainText property (it's renamed to 'content')
+  - Embed arrays use color hex values instead of an integer
+  - Old embed format will still work

+
+### Added
+
+- NadekoBot now supports mysql, postgresql and sqlite
+  - To change the db nadeko will use, simply change the `db type` in `creds.yml`
+  - There is no migration code right now, which means that if you want to switch to another system you'll either have to manually export/import your database or start fresh

+  - They can be load/unloaded/updated at runtime without restarting the bot
+
+### Changed
+
+- Minor club rework
+  - Clubs names are now case sensitive (owo and OwO can be 2 different clubs)
+  - Removed discriminators
+    - Current discriminators which are greater than 1 are appended to clubnames to avoid duplicates, you can rename your club with `.clubrename` to remove it
+    - Most of the clubs with #1 discriminator no longer have it (For example MyClub#1 will now just be MyClub)
+- [dev] A lot of refactoring and slight functionality changes within Nadeko's behavior system and command handler which were required in order to support the medusa system
+
+### Removed
+
+  - Removed `.clublevelreq` command as it doesn't serve much purpose

+  - Expression command now start with ex/expr and end with the name of the action or setting. 
+  - For example `.exd` (`.dcr`) is expression delete, `.exa` (`.acr`)
+  - Permissions (`.lp`) be automatically updated with "ACTUALEXPRESSIONS", "EXPRESSIONS" instead of "ACTUALCUSTOMREACTIONS" and "CUSTOMREACTIONS"
+  - Permissions for `.ecr` (now `.exe`), `.scr` (now `.exs`), `.dcr` (now `.exd`), `.acr` (now `.exa`), `.lcr` (now `.exl`) will be automatically updated

+
+## Running Nadeko
+
+While there are two run modes built into the installer, these options only run Nadeko within the current session. Below are 3 methods of running Nadeko as a background process.
+
+### Tmux Method (Preferred)
+
+Using `tmux` is the simplest method, and is therefore recommended for most users.
+
+**Before proceeding, make sure your bot is not running by either running `.die` in your Discord server or exiting the process with `Ctrl+C`.**
+
+If you are presented with the installer main menu, exit it by choosing Option `8`.
+
+1. Create a new session: `tmux new -s nadeko`
+
+The above command will create a new session named **nadeko** *(you can replace “nadeko” with anything you prefer, it's your session name)*.
+
+2. Navigate to the project's root directory
+    - Project root directory location example: `cd /home/user/nadekobot/`
+3. Enter the `output` directory:
+    - `cd output`
+4. Run the bot using:
+    - `dotnet NadekoBot.dll`
+5. Detatch the tmux session:
+    - Press `Ctrl` + `B`
+    - Then press `D`
+Now check your Discord server, the bot should be online. Nadeko should now be running in the background of your system. 
+
+To re-open the tmux session to either update, restart, or whatever, execute `tmux a -t nadeko`. *(Make sure to replace "nadeko" with your session name. If you didn't change it, leave it as it.)*
+
+
+### Systemd
+
+Compared to using tmux, this method requires a little bit more work to set up, but has the benefit of allowing Nadeko to automatically start back up after a system reboot or the execution of the `.die` command.
+
+1. Navigate to the project's root directory
+    - Project root directory location example: `/home/user/nadekobot/`
+2. Use the following command to create a service that will be used to start Nadeko:
+
+    ```bash
+    echo "[Unit]
+    Description=NadekoBot service
+    After=network.target
+    StartLimitIntervalSec=60
+    StartLimitBurst=2
+    
+    [Service]
+    Type=simple
+    User=$USER
+    WorkingDirectory=$PWD/output
+    # If you want Nadeko to be compiled prior to every startup, uncomment the lines
+    # below. Note  that it's not neccessary unless you are personally modifying the
+    # source code.
+    #ExecStartPre=/usr/bin/dotnet build ../src/NadekoBot/NadekoBot.csproj -c Release -o output/
+    ExecStart=/usr/bin/dotnet NadekoBot.dll
+    Restart=on-failure
+    RestartSec=5
+    StandardOutput=syslog
+    StandardError=syslog
+    SyslogIdentifier=NadekoBot
+    
+    [Install]
+    WantedBy=multi-user.target" | sudo tee /etc/systemd/system/nadeko.service
+    ```
+    
+3. Make the new service available:
+    - `sudo systemctl daemon-reload`
+4. Start Nadeko:
+    - `sudo systemctl start nadeko.service && sudo systemctl enable nadeko.service`
+    
+
+### Systemd + Script
+
+This method is similar to the one above, but requires one extra step, with the added benefit of better error logging and control over what happens before and after the startup of Nadeko.
+
+1. Locate the project and move to its parent directory
+    - Project location example: `/home/user/nadekobot/`
+    - Parent directory example: `/home/user/`
+2. Use the following command to create a service that will be used to execute `NadekoRun.sh`:
+
+    ```bash
+    echo "[Unit]
+    Description=NadekoBot service
+    After=network.target
+    StartLimitIntervalSec=60
+    StartLimitBurst=2
+    
+    [Service]
+    Type=simple
+    User=$USER
+    WorkingDirectory=$_WORKING_DIR
+    ExecStart=/bin/bash NadekoRun.sh
+    Restart=on-failure
+    RestartSec=5
+    StandardOutput=syslog
+    StandardError=syslog
+    SyslogIdentifier=NadekoBot
+    
+    [Install]
+    WantedBy=multi-user.target" | sudo tee /etc/systemd/system/nadeko.service
+    ```
+    
+3. Make the new service available:
+    - `sudo systemctl daemon-reload`
+4. Use the following command to create a script that will be used to start Nadeko:
+    
+    ```bash
+    {
+    echo '#!/bin/bash'
+    echo ""
+    echo "echo \"Running NadekoBot in the background with auto restart\"
+    youtube-dl -U
+    
+    # If you want Nadeko to be compiled prior to every startup, uncomment the lines
+    # below. Note  that it's not necessary unless you are personally modifying the
+    # source code.
+    #echo \"Compiling NadekoBot...\"
+    #cd \"$PWD\"/nadekobot
+    #dotnet build src/NadekoBot/NadekoBot.csproj -c Release -o output/
+
+    echo \"Starting NadekoBot...\"
+    
+    while true; do
+        if [[ -d $PWD/nadekobot/output ]]; then
+            cd $PWD/nadekobot/output || {
+                echo \"Failed to change working directory to $PWD/nadekobot/output\" >&2
+                echo \"Ensure that the working directory inside of '/etc/systemd/system/nadeko.service' is correct\"
+                echo \"Exiting...\"
+                exit 1
+            }
+        else
+            echo \"$PWD/nadekobot/output doesn't exist\"
+            exit 1
+        fi
+        
+        dotnet NadekoBot.dll || {
+            echo \"An error occurred when trying to start NadekBot\"
+            echo \"Exiting...\"
+            exit 1
+        }
+        
+        echo \"Waiting for 5 seconds...\"
+        sleep 5
+        youtube-dl -U
+        echo \"Restarting NadekoBot...\"
+    done
+    
+    echo \"Stopping NadekoBot...\""
+    } > NadekoRun.sh
+    ```
+    
+5. Start Nadeko:
+    - `sudo systemctl start nadeko.service && sudo systemctl enable nadeko.service`
+
+### Setting up Nadeko on a Linux VPS (Digital Ocean Droplet)
+
+If you want Nadeko to play music for you 24/7 without having to hosting it on your PC and want to keep it cheap, reliable and convenient as possible, you can try Nadeko on Linux Digital Ocean Droplet using the link [DigitalOcean](http://m.do.co/c/46b4d3d44795/) (by using this link, you will get **$10 credit** and also support Nadeko)
+
+**Setting up NadekoBot**
+Assuming you have followed the link above to setup an account and a Droplet with a 64-bit operational system on Digital Ocean and got the `IP address and root password (in your e-mail)` to login, it's time to get started.
+
+**This section is only relevant to those who want to host Nadeko on DigitalOcean. Go through this whole section before setting the bot up.**
+
+#### Prerequisites
+
+- Download [PuTTY](http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html)
+- Download [WinSCP](https://winscp.net/eng/download.php) *(optional)*
+- [Create and invite the bot](../../creds-guide).
+
+#### Starting up
+
+- **Open PuTTY** and paste or enter your `IP address` and then click **Open**.  
+  If you entered your Droplets IP address correctly, it should show **login as:** in a newly opened window.
+- Now for **login as:**, type `root` and press enter.
+- It should then ask for a password. Type the `root password` you have received in your e-mail address, then press Enter.
+
+If you are running your droplet for the first time, it will most likely ask you to change your root password. To do that, copy the **password you've received by e-mail** and paste it on PuTTY.
+
+- To paste, just right-click the window (it won't show any changes on the screen), then press Enter.
+- Type a **new password** somewhere, copy and paste it on PuTTY. Press Enter then paste it again.
+
+**Save the new password somewhere safe.**
+
+After that, your droplet should be ready for use. [Follow the guide from the beginning](#linux-from-source) to set Nadeko up on your newly created VPS.

-
-1. In order to migrate a bot hosted **on Linux or from source on Windows**
-    - First update your current version to the latest 2.x version using the 2.x installer
-    - Then you **must** run the bot to prepare the database for the migration, and make sure the bot works prior to upgrade.
- Then:
-2. Rename your old nadeko bot folder to `nadekobot_2x`
-    - `mv NadekoBot nadekobot_2x`
-3. Build the new version and move old data to the output folder 
-    1. Clone the v3 branch to a separate folder 
-        - `git clone https://gitlab.com/kwoth/nadekobot -b v3 --depth 1`
-    2. Build the bot
-        - `dotnet publish -c Release -o output/ src/NadekoBot/`
-    3. Copy old data
-        - ⚠ Be sure you copy the correct command for your system!
-        - **Windows:** `cp -r -fo nadekobot_2x/src/NadekoBot/data nadekobot/src/NadekoBot/data`
-        - **Linux:** `cp -rf nadekobot_2x/src/NadekoBot/data nadekobot/src/NadekoBot/data`
-    4. Copy the database 
-        - `cp nadekobot_2x/src/NadekoBot/bin/Release/netcoreapp2.1/data/NadekoBot.db nadekobot/output/data`
-    5. Copy your credentials
-        - `cp nadekobot_2x/src/NadekoBot/credentials.json nadekobot/output/`
-4. Run the bot
-    - `cd nadekobot/output`
-    - `dotnet NadekoBot.dll`
-5. That's it. Just make sure that when you're updating the bot, you're properly backing up your old data.

+# Creating A Medusa
+
+## Theory
+
+### Introduction
+
+Medusa system allows you to write independent medusae (known as "modules", "cogs" or "plugins" in other software) which you can then load, unload and update at will without restarting the bot.  
+  
+The system itself borrows some design from the current way Nadeko's Modules are written but mostly from never-released `Ayu.Commands` system which was designed to be used for a full Nadeko v3 rewrite. 
+
+The medusa base classes used for development are open source [here](https://gitlab.com/Kwoth/nadekobot/-/tree/v4/src/Nadeko.Medusa) in case you need reference, as there is no generated documentation at the moment.
+
+### Term list
+
+#### Medusa
+
+- The project itself which compiles to a single `.dll` (and some optional auxiliary files), it can contain multiple [Sneks](#snek), [Services](#service), and [ParamParsers](#param-parser)  
+
+#### Snek
+
+- A class which will be added as a single Module to NadekoBot on load. It also acts as a [lifecycle handler](snek-lifecycle.md) and as a singleton service with the support for initialize and cleanup.
+- It can contain a Snek (called SubSnek) but only 1 level of nesting is supported (you can only have a snek contain a subsnek, but a subsnek can't contain any other sneks)
+- Sneks can have their own prefix
+    - For example if you set this to 'test' then a command called 'cmd' will have to be invoked by using `.test cmd` instead of `.cmd` 
+
+#### Snek Command
+
+- Acts as a normal command
+- Has context injected as a first argument which controls where the command can be executed
+    - `AnyContext` the command can be executed in both DMs and Servers
+    - `GuildContext` the command can only be executed in Servers
+    - `DmContext` the command can only be executed in DMs
+- Support the usual features such as default values, leftover, params, etc.
+- It also supports dependency injection via `[inject]` attribute. These dependencies must come after the context and before any input parameters
+- Supports `ValueTask`, `Task`, `Task<T>` and `void` return types
+
+#### Param Parser
+
+- Allows custom parsing of command arguments into your own types.
+- Overriding existing parsers (for example for IGuildUser, etc...) can cause issues.
+
+#### Service
+
+- Usually not needed.
+- They are marked with a `[svc]` attribute, and offer a way to inject dependencies to different parts of your medusa. 
+- Transient and Singleton lifetimes are supported.
+
+### Localization
+
+Response and command strings can be kept in one of three different places based on whether you plan to allow support for localization
+
+option 1) `res.yml` and `cmds.yml`  
+
+If you don't plan on having your app localized, but you just *may* in the future, you should keep your strings in the `res.yml` and `cmds.yml` file the root folder of your project, and they will be automatically copied to the output whenever you build your medusa.
+
+##### Example project folder structure:
+    - uwu/
+        - uwu.csproj
+        - uwu.cs
+        - res.yml
+        - cmds.yml  
+
+##### Example output folder structure:
+    - medusae/uwu/  
+        - uwu.dll  
+        - res.yml  
+        - cmds.yml
+
+option 2) `strings` folder  
+
+If you plan on having your app localized (or want to allow your consumers to easily add languages themselves), you should keep your response strings in the `strings/res/en-us.yml` and your command strings in `strings/cmds/en-us.yml` file. This will be your base file, and from there you can make support for additional languages, for example `strings/res/ru-ru.yml` and `strings/cmds/ru-ru.yml`
+
+##### Example project folder structure:
+    - uwu/
+        - uwu.csproj
+        - uwu.cs
+        - strings/
+            - res/
+                - en-us.yml
+                - ru-ru.yml
+            - cmds/
+                - en-us.yml
+                - ru-ru.yml
+
+##### Example output folder structure:
+    - medusae/uwu/
+        - uwu.dll
+        - strings/
+            - res/
+                - en-us.yml
+                - ru-ru.yml
+            - cmds/
+                - en-us.yml
+                - ru-ru.yml
+
+option 3) In the code  
+
+If you don't want any auxiliary files, and you don't want to bother making new .yml files to keep your strings in, you can specify the command strings directly in the `[cmd]` attribute itself, and use non-localized methods for message sending in your commands.
+
+If you update your response strings .yml file(s) while the medusa is loaded and running, running `.stringsreload` will reload the responses without the need to reload the medusa or restart the bot.
+
+#### Config
+
+- Medusa config is kept in `medusae/medusa.yml` file
+- At the moment this config only keeps track of which medusae are currently loaded (they will also be always loaded at startup)
+- If a medusa is causing issues and you're unable to unload it, you can remove it from the `loaded:` list in this config file and restart the bot. It won't be loaded next time the bot is started up
+
+#### Unloadability issues  
+
+To make sure your medusa can be properly unloaded/reloaded you must:
+
+-  Make sure that none of your types and objects are referenced by the Bot or Bot's services after the DisposeAsync is called on your Snek instances. 
+
+- Make sure that all of your commands execute quickly and don't have any long running tasks, as they will hold a reference to a type from your assembly
+
+- If you are still having issues, you can always run `.meunload` followed by a bot restart, or if you want to find what is causing the medusa unloadability issues, you can check the [microsoft's assembly unloadability debugging guide](https://docs.microsoft.com/en-us/dotnet/standard/assembly/unloadability)
+
+## Practice
+
+This section will guide you through how to create a simple custom medusa. You can find the entirety of this code hosted [here](https://gitlab.com/nadeko/example_medusa)
+
+#### Prerequisite
+- [.net6 sdk](https://dotnet.microsoft.com/en-us/download) installed
+- Optional: use [vscode](https://code.visualstudio.com/download) to write code
+
+#### Guide
+
+
+- Open your favorite terminal and navigate to a folder where you will keep your project .
+
+- Create a new folder 
+    - `mkdir example_medusa`
+- Create a new .net class library
+    - `dotnet new classlib`
+- Open the current folder with your favorite editor/IDE. In this case we'll use VsCode
+    - `code .`
+- Remove the `Class1.cs` file
+- Replace the contents of the `.csproj` file with the following contents
+```xml
+<Project Sdk="Microsoft.NET.Sdk">
+    <PropertyGroup>
+        <TargetFramework>net6.0</TargetFramework>

+          the gitlab.com/kwoth/nadekobot repo locally and reference the NadekoBot.csproj because there is no NadekoBot package atm.
+          It is strongly recommended that you checkout a specific tag which matches your version of nadeko,
+          as there could be breaking changes even between minor versions of NadekoBot.
+          For example if you're running NadekoBot 4.1.0 locally for which you want to create a medusa for,
+          you should do "git checkout 4.1.0" in your NadekoBot solution and then reference the NadekoBot.csproj
+        -->

+            <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
+        </None>
+    </ItemGroup>
+</Project>
+
+```
+- Create a `MySnek.cs` file and add the following contents
+```cs
+using Nadeko.Snake;
+using NadekoBot;
+using Discord;
+
+public sealed class MySnek : Snek
+{
+    [cmd]
+    public async Task Hello(AnyContext ctx)
+    {
+        await ctx.Channel.SendMessageAsync($"Hello everyone!");
+    }

+    [cmd]
+    public async Task Hello(AnyContext ctx, IUser target)
+    {
+        await ctx.ConfirmLocalizedAsync("hello", target);
+    }
+}
+```
+- Create `res.yml` and `cmds.yml` files with the following contents
+`res.yml`
+```yml
+medusa.description: "This is my medusa's description"
+hello: "Hello {0}, from res.yml!"
+```
+
+`cmds.yml`
+```yml
+hello: 
+  desc: "This is a basic hello command"
+  args:
+    - ""
+    - "@Someone"
+```
+
+- Add `NuGet.Config` file which will let you use the base Nadeko.Medusa package. This file should always look like this and you shouldn't change it
+
+```xml
+<configuration>
+    <packageSources>
+        <add key="nuget.org" value="https://api.nuget.org/v3/index.json" protocolVersion="3" />
+        <add key="nadeko.bot" value="https://www.myget.org/F/nadeko/api/v3/index.json" protocolVersion="3" />
+    </packageSources>
+</configuration>
+```
+
+### Build it
+
+- Build your Medusa into a dll that Nadeko can load. In your terminal, type:
+    - `dotnet publish -o bin/medusae/example_medusa /p:DebugType=embedded`
+
+- Done. You can now try it out in action.
+
+### Try it out
+
+- Copy the `bin/medusae/example_medusa` folder into your NadekoBot's `data/medusae/` folder. (Nadeko version 4.1.0+)
+
+- Load it with `.meload example_medusa`
+
+- In the channel your bot can see, run the following commands to try it out
+    - `.hello` and
+    - `.hello @<someone>`
+
+- Check its information with
+    - `.meinfo example_medusa`
+
+- Unload it
+    - `.meunload example_medusa`
+
+- Congrats! You've just made your first medusa!

+## Getting Started
+
+### What is the Medusa system?
+
+- It is a dynamic module/plugin/cog system for NadekoBot introduced in **NadekoBot 4.1.0**  
+
+- Allows developers to add custom functionality to Nadeko without modifying the original code  
+
+- Allows for those custom features to be updated during bot runtime (if properly written), without the need for bot restart.
+
+- They are added to `data/medusae` folder and are loaded, unloaded and handled through discord commands.  
+    - `.meload` Loads the specified medusa (see `.h .meload`)
+    - `.meunload` Unloads the specified medusa (see `.h .meunload`)
+    - `.meinfo` Checks medusae information (see `.h .meinfo`)
+    - `.melist` Lists the available medusae (see `.h .melist`)
+
+### How to make one?
+
+Medusae are written in [C#](https://docs.microsoft.com/en-us/dotnet/csharp/tour-of-csharp/) programming language, so you will need at least low-intermediate knowledge of it in order to make a useful Medusa.
+
+Follow the [creating a medusa guide](creating-a-medusa.md)
+
+### Where to get medusae other people made?
+
+⚠ *It is EXTREMELY, and I repeat **EXTREMELY** dangerous to run medusae of strangers or people you don't FULLY trust.* ⚠  
+⚠ *It can not only lead to your bot being stolen, but it also puts your entire computer and personal files in jeopardy.* ⚠
+
+**It is strongly recommended to run only the medusae you yourself wrote, and only on a hosted VPS or dedicated server which ONLY hosts your bot, to minimize the potential damage caused by bad actors.**
+
+No easy way at the moment, except asking in the `#dev-and-modding` chat in [#NadekoLog server](https://discord.nadeko.bot)

+# Snek Lifecycle  
+
+*You can override several methods to hook into command handler's lifecycle.  
+These methods start with `Exec*`*
+
+
+- `ExecOnMessageAsync` runs first right after any message was received  
+- `ExecInputTransformAsync` runs after ExecOnMessageAsync and allows you to transform the message content before the bot looks for the matching command  
+- `ExecPreCommandAsync` runs after a command was found but not executed, allowing you to potentially prevent command execution  
+- `ExecPostCommandAsync` runs if the command was successfully executed  
+- `ExecOnNoCommandAsync` runs instead of ExecPostCommandAsync if no command was found for a message  
+
+
+*Besides that, sneks have 2 methods with which you can initialize and cleanup your snek*  
+
+
+- `InitializeAsync` Runs when the medusa which contains this snek is being loaded  
+- `DisposeAsync` Runs when the medusa which contains this snek is being unloaded

+## Votes Api
+
+This api is used if you want your bot to be able to reward users who vote for it on discords.com or top.gg   
+
+#### [GET] `/discords/new`
+    Get the discords votes received after previous call to this endpoint.
+    Input full url of this endpoint in your creds.yml file under Discords url field.
+    For example "https://api.my.cool.bot/discords/new"
+#### [GET] `/topgg/new`
+    Get the topgg votes received after previous call to this endpoint.
+    Input full url of this endpoint in your creds.yml file under Topgg url field.
+    For example "https://api.my.cool.bot/topgg/new"
+
+#### [POST] `/discordswebhook`
+    Input this endpoint as the webhook on discords.com bot edit page
+    model: https://docs.botsfordiscord.com/methods/receiving-votes
+    For example "https://api.my.cool.bot/topggwebhook"
+#### [POST] `/topggwebhook`
+    Input this endpoint as the webhook https://top.gg/bot/:your-bot-id/webhooks (replace :your-bot-id with your bot's id)
+    model: https://docs.top.gg/resources/webhooks/#schema
+    For example "https://api.my.cool.bot/discordswebhook"
+
+Input your super-secret header value in appsettings.json's DiscordsKey and TopGGKey fields
+They must match your DiscordsKey and TopGG key respectively, as well as your secrets in the discords.com and top.gg webhook setup pages
+
+Full Example:
+
+⚠ Change TopggKey and DiscordsKey to a secure long string  
+⚠ You can use https://www.random.org/strings/?num=1&len=20&digits=on&upperalpha=on&loweralpha=on&unique=on&format=html&rnd=new to generate it
+
+`creds.yml`

+*** Please enable privileged intents ***
+
+Certain Nadeko features require Discord's privileged gateway intents.
+These include greeting and goodbye messages, as well as creating the Owner message channels for DM forwarding.
+
+How to enable privileged intents:
+1. Head over to the Discord Developer Portal https://discord.com/developers/applications/
+2. Select your Application.
+3. Click on `Bot` in the left side navigation panel, and scroll down to the intents section.
+4. Enable all intents.
+5. Restart your bot.
+
+Read this only if your bot is in 100 or more servers:
+
+You'll need to apply to use the intents with Discord, but for small selfhosts, all that is required is enabling the intents in the developer portal.
+Yes, this is a new thing from Discord, as of October 2020. No, there's nothing we can do about it. Yes, we're aware it worked before.
+While waiting for your bot to be accepted, you can change the 'usePrivilegedIntents' inside your creds.yml to 'false', although this will break many of the nadeko's features");
