 # Modmail for Discord
-A bot for [Discord](https://discordapp.com/) that allows users to DM the bot to contact the server's entire mod team.
-These DMs get relayed to a modmail server where each user gets their own channel, or "thread".
-Moderators and admins can then reply to these threads, and these responses are relayed back to the original user as a DM.
+A bot for [Discord](https://discordapp.com/) that allows users to DM the bot to contact the server's moderators/staff
+without messaging them individually or pinging them publically on the server.
+These DMs get relayed to modmail *threads*, channels where staff members can reply to and talk with the user.
+To the user, the entire process happens in DMs with the bot.
 
 Inspired by Reddit's modmail system.

-## Plugins
-The bot supports loading external plugins.
-
-### Specifying plugins to load
-Add the path to the plugin's file to the `plugins` array in the config.
-The plugin will be automatically loaded on startup.
-The path is relative to the bot's folder.
-
-### Creating a plugin
-Create a `.js` file that exports a function.
-This function will be called when the plugin is loaded with an object that has the following properties:
-* `bot` - the [Eris Client object](https://abal.moe/Eris/docs/Client)
-* `knex` - the [Knex database object](https://knexjs.org/#Builder)
-* `config` - the loaded config
-* `commands` - an object with functions to add and manage commands
-* `attachments` - an object with functions to save attachments and manage attachment storage types
-
-See [src/plugins.js#L4](src/plugins.js#L4) for more details
-
-#### Example plugin file
-This example adds a command `!mycommand` that replies with `"Reply from my custom plugin!"` when the command is used inside a modmail inbox thread channel.
-```js
-module.exports = function({ bot, knex, config, commands }) {
-  commands.addInboxThreadCommand('mycommand', [], (msg, args, thread) => {
-    thread.replyToUser(msg.author, 'Reply from my custom plugin!');
-  });
-}
-```
-
-(Note the use of [object destructuring](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#Unpacking_fields_from_objects_passed_as_function_parameter) in the function parameters)
-
-#### Example of a custom attachment storage type
-This example adds a custom type for the `attachmentStorage` option called `"original"` that simply returns the original attachment URL without rehosting it in any way.
-```js
-module.exports = function({ attachments }) {
-  attachments.addStorageType('original', attachment => {
-    return { url: attachment.url };
-  });
-};
-```
-To use this custom attachment storage type, you would set the `attachmentStorage` config option to `"original"`.
-
-### Work in progress
-The current plugin API is fairly rudimentary and will be expanded in the future.
-The API can change in non-major releases during this early stage. Keep an eye on [CHANGELOG.md](CHANGELOG.md) for any changes.
-
-Please send any feature suggestions to the [issue tracker](https://github.com/Dragory/modmailbot/issues)!

+# 📝 Configuration
+Haven't set up the bot yet? Check out [Setting up the bot](setup.md) first!
+
+## Table of contents
+- [Configuration file](#configuration-file) (start here)
+- [Adding new options](#adding-new-options)
+- [Required options](#required-options)
+- [Other options](#other-options)
+- [config.ini vs config.json](#configini-vs-configjson)
+
+## Configuration file
+All bot options are saved in a configuration file in the bot's folder.
+This is created during the [setup](setup.md) and is generally either `config.ini` or, if you've been using the bot for
+longer, `config.json`.
+
+The instructions on this page are for `config.ini` but can be adapted to `config.json` as well.
+See [config.ini vs config.json](#configini-vs-configjson) for more details.
+Note that the format of `.ini` and `.json` are different -- you can't simply rename a `.json` to `.ini` or
+vice versa.
+
+## Adding new options
+To add a new option to your `config.ini`, open the file in a text editor such as notepad.
+Each option is put on a new line, and follows the format `option = value`. For example, `mainGuildId = 1234`.
+
+**You need to restart the bot for configuration changes to take effect!**
+
+You can add comments in the config file by prefixing the line with `#`. Example:
+```ini
+# This is a comment
+option = value
+```
+
+### Toggle options
+Some options like `allowMove` are "**Toggle options**": they control whether certain features are enabled (on) or not (off).
+* To enable a toggle option, set its value to `on`, `true`, or `1`
+* To disable a toggle option, set its value to `off`, `false`, or `0`
+* E.g. `allowMove = on` or `allowMove = off`
+
+### "Accepts multiple values"
+Some options are marked as "**Accepts multiple values**". To give these options multiple values,
+write the option as `option[] = value` and repeat for every value. For example:
+
+```ini
+inboxServerPermission[] = kickMembers
+inboxServerPermission[] = manageMessages
+```
+
+You can also give these options a single value in the usual way, i.e. `inboxServerPermission = kickMembers`
+
+### Multiple lines of text
+For some options, such as `greetingMessage`, you might want to add text that spans multiple lines.
+To do that, use the same format as with "Accepts multiple values" above:
+
+```ini
+greetingMessage[] = Welcome to the server!
+greetingMessage[] = This is the second line of the greeting.
+greetingMessage[] = 
+greetingMessage[] = Fourth line! With an empty line in the middle.
+```
+
+## Required options

+If enabled, all messages in modmail threads will be sent to the user without having to use `!r`.  
+To send internal messages in the thread when this option is enabled, prefix them with `!note` (using your `prefix`),
+e.g. `!note This is an internal message`.
+
+#### alwaysReplyAnon
+**Default:** `off`  
+If `alwaysReply` is enabled, this option controls whether the auto-reply is anonymous
+
+#### attachmentStorage

+**Default:** `You haven't been a member of the server for long enough to contact modmail.`  
+If `requiredTimeOnServer` is set, users that are too new will be sent this message if they try to message modmail.
+
+#### mentionRole
+**Default:** `here`  
+**Accepts multiple values.** Role that is mentioned when new threads are created or the bot is mentioned.
+Accepted values are "here", "everyone", or a role id.
+Requires `pingOnBotMention` to be enabled.
+Set to an empty value (`mentionRole=`) to disable these pings entirely.
+
+#### mentionUserInThreadHeader
+**Default:** `off`  
+If enabled, mentions the user messaging modmail in the modmail thread's header.
+
+#### newThreadCategoryId
+**Default:** *None*  
+**Deprecated.** Same as `categoryAutomation.newThread`.

+**Default:** `on`  
+If enabled, the bot will mention staff (see `mentionRole` option) on the inbox server when the bot is mentioned on the main server.
+
+#### plugins
+**Default:** *None*  
+**Accepts multiple values.** External plugins to load on startup. See [Plugins](plugins.md) for more information.
+
+#### port
+**Default:** `8890`  
+Port to use for attachments (when `attachmentStorage` is set to `local`) and logs.  
+Make sure to do the necessary [port forwarding](https://portforward.com/) and add any needed firewall exceptions so the port is accessible from the internet.
+
+#### prefix
+**Default:** `!`  
+Prefix for bot commands
+
+#### relaySmallAttachmentsAsAttachments
+**Default:** `off`  
+If enabled, small attachments from users are sent as real attachments rather than links in modmail threads.
+The limit for "small" is 2MB by default; you can change this with the `smallAttachmentLimit` option.
+
+#### requiredAccountAge
+**Default:** *None*  
+Required account age for contacting modmail (in hours). If the account is not old enough, a new thread will not be created and the bot will reply with `accountAgeDeniedMessage` (if set) instead.
+
+#### requiredTimeOnServer
+**Default:** *None*  
+Required amount of time (in minutes) the user must be a member of the server before being able to contact modmail. If the user hasn't been a member of the server for the specified time, a new thread will not be created and the bot will reply with `timeOnServerDeniedMessage` (if set) instead.
+
+#### responseMessage
+**Default:** `Thank you for your message! Our mod team will reply to you here as soon as possible.`  
+The bot's response to the user when they message the bot and open a new modmail thread

+Prefix to use snippets anonymously
+
+#### status

+The bot's "Playing" text
+
+#### syncPermissionsOnMove
+**Default:** `on`  
+If enabled, channel permissions for the thread are synchronized with the category when using `!move`. Requires `allowMove` to be enabled.
+
+#### threadTimestamps
+**Default:** `off`  
+If enabled, modmail threads will show accurate UTC timestamps for each message, in addition to Discord's own timestamps.
+Logs show these always, regardless of this setting.
+
+#### typingProxy
+**Default:** `off`  
+If enabled, any time a user is typing to modmail in their DMs, the modmail thread will show the bot as "typing"

+
+#### useNicknames
+**Default:** `off`  
+If enabled, mod replies will use their nicknames (on the inbox server) instead of their usernames
+
+## config.ini vs config.json
+Earlier versions of the bot instructed you to create a `config.json` instead of a `config.ini`.
+**This is still fully supported, and will be in the future as well.**
+However, there are some differences between `config.ini` and `config.json`.
+
+### Formatting
+*See [the example on the Wikipedia page for JSON](https://en.wikipedia.org/wiki/JSON#Example)
+for a general overview of the JSON format.*
+
+* In `config.json`, all text values and IDs need to be wrapped in quotes, e.g. `"mainGuildId": "94882524378968064"`
+* In `config.json`, all numbers (other than IDs) are written without quotes, e.g. `"port": 3000`
+
+### Toggle options
+In `config.json`, valid values for toggle options are `true` and `false` (not quoted),
+which correspond to `on` and `off` in `config.ini`.
+
+### "Accepts multiple values"
+Multiple values are specified in `config.json` using arrays:
+```json
+{
+  "inboxPermission": [
+    "kickMembers",
+    "manageMessages"
+  ]
+}
+```
+
+### Multiple lines of text
+Since `config.json` is parsed using [JSON5](https://json5.org/), multiple lines of text are supported
+by escaping the newline with a backslash (`\ `):
+```json5
+{
+  "greetingMessage": "Welcome to the server!\
+This is the second line of the greeting."
+}
+```

+# 🧩 Plugins
+The bot supports loading external plugins.
+
+## Specifying plugins to load
+For each plugin file you'd like to load, add the file path to the [`plugins` option](configuration.md#plugins).
+The path is relative to the bot's folder.
+Plugins are automatically loaded on bot startup.
+
+## Creating a plugin
+Create a `.js` file that exports a function.
+This function will be called when the plugin is loaded, with 1 argument: an object that has the following properties:
+* `bot` - the [Eris Client object](https://abal.moe/Eris/docs/Client)
+* `knex` - the [Knex database object](https://knexjs.org/#Builder)
+* `config` - the loaded config
+* `commands` - an object with functions to add and manage commands
+* `attachments` - an object with functions to save attachments and manage attachment storage types
+
+See [src/plugins.js#L4](../src/plugins.js#L4) for more details
+
+### Example plugin file
+This example adds a command `!mycommand` that replies with `"Reply from my custom plugin!"` when the command is used inside a modmail inbox thread channel.
+```js
+module.exports = function({ bot, knex, config, commands }) {
+  commands.addInboxThreadCommand('mycommand', [], (msg, args, thread) => {
+    thread.replyToUser(msg.author, 'Reply from my custom plugin!');
+  });
+}
+```
+
+(Note the use of [object destructuring](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Destructuring_assignment#Unpacking_fields_from_objects_passed_as_function_parameter) in the function parameters)
+
+### Example of a custom attachment storage type
+This example adds a custom type for the `attachmentStorage` option called `"original"` that simply returns the original attachment URL without rehosting it in any way.
+```js
+module.exports = function({ attachments }) {
+  attachments.addStorageType('original', attachment => {
+    return { url: attachment.url };
+  });
+};
+```
+To use this custom attachment storage type, you would set the `attachmentStorage` config option to `"original"`.
+
+## Work in progress
+The current plugin API is fairly rudimentary and will be expanded on in the future.
+The API can change in non-major releases during this early stage. Keep an eye on [CHANGELOG.md](../CHANGELOG.md) for any changes.
+
+Please send any feature suggestions to the [issue tracker](https://github.com/Dragory/modmailbot/issues)!

+# 🛠️ Setting up the bot
+**Note:** This bot is run on your own machine or a server. To keep it online, you need to have the bot process running at all time.
+
+## Terminology
+* **Main server** (or main guild) is the server where users will be contacting modmail from
+* **Inbox server** (or inbox guild, or mail guild) is the server where modmail threads will be created.
+  In a "single-server setup" this is the same server as the main server.
+* A **modmail thread** is a channel on the **inbox server** that contains the current exchange with the **user**.
+  These threads can be closed to archive them. One **user** can only have 1 modmail thread open at once.
+* A **moderator**, in modmail's context, is a server staff member who responds to and manages modmail threads
+* A **user**, in modmail's context, is a Discord user who is contacting modmail by DMing the bot
+
+## Prerequisites
+1. Create a bot account through the [Discord Developer Portal](https://discordapp.com/developers/)
+2. Invite the created bot to your server
+3. Install Node.js 10, 11, or 12
+    - Node.js 13 is currently not supported
+4. Download the latest bot version from [the releases page](https://github.com/Dragory/modmailbot/releases) and extract it to a folder
+5. Make a copy of the file `config.example.ini` in the bot's folder and name the copy `config.ini`
+
+## Single-server setup
+In this setup, modmail threads are opened on the main server in a special category.
+1. Open `config.ini` in a text editor and fill in the required values. `mainGuildId` and `mailGuildId` should both be set to your server's id.
+2. On a new line at the end of `config.ini`, add `categoryAutomation.newThread = CATEGORY_ID_HERE`
+    - Replace `CATEGORY_ID_HERE` with the ID of the category where new modmail threads should go
+3. Make sure the bot has `Manage Channels`, `Manage Messages`, and `Attach Files` permissions in the category
+4. [🏃 Start the bot!](starting-the-bot.md)
+5. Want to change other bot options? See [📝 Configuration](configuration.md).
+
+## Two-server setup
+In this setup, modmail threads are opened on a separate inbox server.
+1. Create an inbox server on Discord
+2. Invite the bot to the inbox server.
+3. Open `config.ini` in a text editor and fill in the values
+4. Make sure the bot has the `Manage Channels`, `Manage Messages`, and `Attach Files` permissions on the **inbox** server
+5. [🏃 Start the bot!](starting-the-bot.md)
+5. Want to change other bot options? See [📝 Configuration](configuration.md).

+# 🏃 Starting the bot
+Haven't set up the bot yet? Check out [Setting up the bot](setup.md) first!
+
+## Windows
+* To start the bot, double-click on `start.bat` in the bot's folder
+* To shut down the bot, close the console window
+* To restart the bot, close the console window and then double-click on `start.bat` again
+
+## Linux / macOS / Advanced on Windows
+The following assumes basic knowledge about using command line tools.
+1. Before first start-up and after every update, run `npm ci` in the bot's folder
+2. Run `npm start` in the bot's folder to start the bot
+
+## Process managers
+If you're using a process manager like PM2, the command to run is `npm start`.
+A PM2 process file, `modmailbot-pm2.json`, is included in the repository.
