 # SupportChild
+
+A support ticket Discord bot. Uses a MySQL database for storage of ticket information. Creates formatted HTML ticket transcripts when tickets are closed.
+
+#### Thanks to [Tyrrrz](https://github.com/Tyrrrz/DiscordChatExporter) for the amazing library used in the transcript function.
+
+## Setup
+
+1. Set up a mysql-compatible server, create a user and empty database for the bot to use.
+
+2. (Optional) Install .NET 9 if it doesn't already exist on your system.
+
+3. Create a new bot application and invite it to your server.
+
+4. Download the bot for your operating system, either a [release version](https://toastielab.dev/toastie-stuff/SupportChild/releases) or a [dev build](https://ci.toastielab.dev/job/toastie-stuff/job/SupportChild/job/main/). Get the normal version if you have installed .NET 8 on your system, get the self contained version otherwise.
+
+| Application                 | Description                                                           |
+|-----------------------------|-----------------------------------------------------------------------|
+| `SupportChild-Linux`          | Standard Linux version.                                               |
+| `SupportChild-SC-Linux`       | Larger Linux version which does not require .NET 9 to be installed.   |
+| `SupportChild-SC-Windows.exe` | Standard Windows version.                                             |
+| `SupportChild-Windows.exe`    | Larger Windows version which does not require .NET 9 to be installed. |
+
+
+5. Run the bot application, `./SupportChild_<version>.exe`, this creates a config file in the current directory.
+
+6. Set up the config, there are instructions inside. If you need more help either contact me in Discord or through an issue here.
+
+7. Restart the bot.
+
+8. Go to `Settings->Integrations->Bot->Command Permissions` in your Discord server to set up permissions for the commands.
