You can also browse this source code online and clone the wasmtime
repository to run the example locally:

* [Rust](https://github.com/bytecodealliance/wasmtime/blob/main/examples/hello.rs)
* [C](https://github.com/bytecodealliance/wasmtime/blob/main/examples/hello.c)
* [C++](https://github.com/bytecodealliance/wasmtime/blob/main/examples/hello.cc)

This example shows off how to instantiate a simple wasm module and interact with
it.
