 # discord-music-bot
 
-Discord bot made in Rust using serenity and lavalink-rs
+Discord music bot template written in NodeJS using `discord.js` and `erela.js`, with Lavalink support.
+
+## Features
+
+- Slash commands: `/ping`, `/join`, `/play`, `/leave`  
+- Lavalink integration for audio playback  
+- Modular command handler structure  
+
+## Prerequisites
+
+- Node.js (>=14)  
+- pnpm or npm  
+- A Discord application with bot token  
+- LavaLink server for audio streaming  
+
+## Setup
+
+1. Copy `.env.example` to `.env` and fill in your credentials:
+   ```env
+   DISCORD_TOKEN=your_discord_bot_token
+   CLIENT_ID=your_discord_application_id
+   LAVALINK_HOST=127.0.0.1
+   LAVALINK_PORT=2333
+   LAVALINK_PASSWORD=your_lavalink_password
+   ```
+2. Install dependencies:
+   ```sh
+   pnpm install
+   ```
+3. Run tests:
+   ```sh
+   pnpm test
+   ```
+4. Register slash commands:
+   ```sh
+   pnpm start # or node deploy-commands.js
+   ```
+5. Start the bot:
+   ```sh
+   pnpm start
+   ```
+
+## Docker
+
+A `Dockerfile` and `docker-compose.yml` are provided for containerized deployment.
+
+- Build and run with Docker Compose:
+  ```sh
+  docker-compose up --build
+  ```
+- Environment variables are loaded from `.env`.  
+- Lavalink service is configured in `docker-compose.yml` alongside the bot.
+
+## Project Structure
+
+- `src/index.js` — Entry point  
+- `src/commands/` — Slash command modules  
+- `src/events/` — Discord event handlers  
+- `src/structures/` — Erela.js (Lavalink) event wiring  
+- `src/utils/logger.js` — Logging setup  
+- `deploy-commands.js` — Slash command registration script  
+- `Dockerfile` — Bot container image  
+- `docker-compose.yml` — Multi-service setup (bot + Lavalink)
