 A simple example in which we spawn a worker and tell it to call a certain rust function.
 
 To run this example, `cd` into this directory and then:
-```rust
-> cargo build --release
-> wasm-bindgen ../target/wasm32-unknown-unknown/release/call_to_rust.wasm --target=no-modules --out-dir=pkg
-> python ../server.py
+```sh
+cargo install --version 0.2.81 wasm-bindgen-cli --force # if you aren't getting it from the nix flake
+cargo build --release
+wasm-bindgen ../target/wasm32-unknown-unknown/release/call_to_rust.wasm --target=no-modules --out-dir=pkg
+python ../server.py
 ```
 and then open your browser and go to `http://localhost:8000`.
