Install the App SDK

Download the App SDK zip from /sdk. The kit includes:

• wit/ — the koba:app WIT world
• crates/koba_wasi_sdk/ — capability constants and helpers
• templates/hello/ — a minimal starter app

You need Rust and the wasm32-wasip2 target:

rustup target add wasm32-wasip2

If you want to run apps on real hardware, install KOB3 on a host.
