## Introduction
Pumpkin is an open-source Minecraft server written in Rust that aims to provide a faster, more memory-efficient alternative to the official Java server. It implements the Minecraft protocol from scratch, leveraging Rust's performance characteristics and safety guarantees to handle multiplayer worlds with lower resource consumption.

## What Pumpkin Does
- Implements the Minecraft Java Edition server protocol for multiplayer gameplay
- Handles player connections, world loading, and entity management
- Supports vanilla world generation and chunk loading
- Processes game mechanics including block interactions and player movement
- Provides a plugin system for extending server functionality

## Architecture Overview
Pumpkin is built as an asynchronous Rust application using Tokio for handling concurrent player connections. The server parses Minecraft protocol packets, manages world state in memory with efficient data structures, and writes changes to disk. Its modular architecture separates networking, world management, and game logic into distinct crates within a Cargo workspace.

## Self-Hosting & Configuration
- Clone the repository and build with `cargo run --release`
- Configure server settings via the generated configuration files
- Adjust world generation, view distance, and player limits in the config
- Run behind a proxy like Velocity or BungeeCord for multi-server setups
- Deploy via Docker using the community-maintained container images

## Key Features
- Written in Rust for memory safety and high performance
- Async I/O handles many concurrent players with low overhead
- Modular crate structure allows building custom server configurations
- Implements modern Minecraft protocol versions
- Lower memory and CPU usage compared to vanilla Java servers

## Comparison with Similar Tools
- **Vanilla Minecraft Server (Java)** — the official server; Pumpkin aims for lower resource usage via Rust
- **Paper/Spigot** — optimized Java forks with large plugin ecosystems; Pumpkin's plugin system is newer
- **Minestom** — lightweight Java server library; Pumpkin takes a similar minimal approach but in Rust
- **Cuberite** — C++ Minecraft server; Pumpkin uses Rust for safer memory management

## FAQ
**Q: Is Pumpkin compatible with existing Minecraft Java clients?**
A: Yes. It implements the Minecraft Java Edition protocol and works with standard clients.

**Q: Can I use Bukkit/Spigot plugins with Pumpkin?**
A: No. Pumpkin has its own plugin API. Existing Java plugins are not compatible.

**Q: Is Pumpkin ready for production use?**
A: It is under active development. Core gameplay works, but some vanilla features may still be in progress.

**Q: How much RAM does Pumpkin use compared to the Java server?**
A: Significantly less. Rust's memory model avoids the JVM's garbage collection overhead, resulting in a smaller and more predictable memory footprint.
