Building from Source

• Install Rust
• [Linux/unix] Make sure perl is installed¹
• Clone the repository
• Run cargo build --release
• The executable will be located in target/release

---

Note for server owners:

When the launcher updates itself on Windows it will restart by spawning a new console. If you are automating this process, you should probably use --skip-launcher-update and download the latest launcher yourself from here.

The linux build does not update itself.
