 #### wasm-bindgen
 
+- Install nightly toolchain and dependencies:
+```bash
+rustup toolchain install nightly
+rustup component add rust-src --toolchain nightly
+cargo install wasm-bindgen-cli
+```
 - Build with `./build_wasm.sh` (bash) or `./build_wasm.ps1` (PowerShell). This custom build step is required because prebuilt standard library does not have support for atomics yet. Read more about this [here](https://rustwasm.github.io/2018/10/24/multithreading-rust-and-wasm.html).
 - Serve `examples` directory over HTTP with cross-origin isolation enabled and open `simple.html` in the browser. Inspect console output. You can use `cargo install sfz` as a basic HTTP server and serve with `sfz examples --coi`.
 
 #### wasm-pack
 
-- Build with `./examples-wasm-pack/web-build.sh` for an example targeting `web`, and `./examples/wasm-pack/web-build-no-module.sh` for an example targeting `no-modules`.
+- Install `wasm-pack`:
+```bash
+cargo install wasm-pack
+```
+- Build with `./examples-wasm-pack/web-build.sh` for an example targeting `web`, and `./examples-wasm-pack/web-build-no-module.sh` for an example targeting `no-modules`.
 - Serve `./examples-wasm-pack/module` or `./examples-wasm-pack/no-module`, respectively, over HTTP and open `simple.html` in browser. Inspect console output.
