 # discord-music-bot
 
-Discord music bot template written 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
+- Lavalink integration for audio playback  
 - Modular command handler structure  
 
 ## Prerequisites
-- Rust (stable toolchain)
+
+- Node.js (>=14)  
+- pnpm or npm  
 - A Discord application with bot token  
-- LavaLink server running (see [LavaLink](https://github.com/freyacodes/Lavalink))
+- 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. Build the project:
+2. Install dependencies:
    ```sh
-   cargo build --release
+   pnpm install
+   ```
+3. Run tests:
+   ```sh
+   npm test
+   ```
+4. Register slash commands:
+   ```sh
+   npm start # or node deploy-commands.js
+   ```
+5. Start the bot:
+   ```sh
+   npm start
    ```
 
-3. Run the bot:
-   ```sh
-   cargo run --release
-   ```
+## 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/main.rs` - Bot entry point, initializes Serenity and LavaLink clients
-- `src/handler.rs` - Serenity event handlers (ready, interaction, voice updates)
-- `src/lavalink_handler.rs` - LavaLink event handlers
-- `src/state.rs` - TypeMap keys for shared state
-- `src/utils.rs` - Utility functions (env management)
-- `src/commands/` - Modular slash command definitions and handlers
-
-## Commands
-
-- `/ping` - Replies with "Pong!"
-- `/join` - Bot joins your voice channel
-- `/play url:<URL>` - Plays audio from the given URL
-- `/leave` - Bot leaves the voice channel
-
-## TODO
-- Implement actual command logic in `src/commands/*.rs`
-- Add error handling and command concurrency management
-- Expand LavaLink event handlers
+- `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)
