Looks interesting. Just a reminder: please update the `Crystal` section the [https://github.com/wasmerio/wasmer/README.md](https://github.com/wasmerio/wasmer/README.md) file. 🙂

Thanks. [wasmer](https://github.com/wasmerio/wasmer) is already reflecting this shard on its README

What is meant by “_no published package_” for Crystal (i.e.: `wasmer-crystal`) on [GitHub - wasmerio/wasmer: 🚀 The leading WebAssembly Runtime supporting WASI and Emscripten](https://github.com/wasmerio/wasmer) ?

On [Releases · naqvis/wasmer-crystal · GitHub](https://github.com/naqvis/wasmer-crystal/releases), there are 2 releases. Does `wasmer-crystal` lack some features or does `wasmer` just need to update their doc’s? (I don’t know enough about it either; just wondering.)

Packages on that site represents **standalone** packages, which doesn’t require any pre-requisite like have `wasmer` runtime installed etc. As all entries listed under **Package** columns comes either bundled with runtime or they are created in **Rust**.
