## Building from Source
First, you will need the WASI target installed in your Rust system:
```shell
rustup target add wasm32-wasi
```
Once WASI is available, you can build the WebAssembly binary by yourself with:
```shell
cargo build --release --target wasm32-wasi
```
This will create a new file located at `target/wasm32-wasi/release/cowsay.wasm`.
When the wasm file is created you can upload it to wasmer or execute it with wasmer:
```shell
wasmer publish
# OR
wasmer run . "Hello World"
```
You can also build a native executable with
```shell
cargo build
```
