# spec

This repository holds the sources for the WebAssembly draft specification

(to seed a future

[WebAssembly Working Group](https://lists.w3.org/Archives/Public/public-new-work/2017Jun/0005.html)),

a reference implementation, and the official testsuite.

A formatted version of the spec is available here:

[webassembly.github.io/spec](https://webassembly.github.io/spec/),

Participation is welcome. Discussions about new features, significant semantic

changes, or any specification change likely to generate substantial discussion

should take place in

[the WebAssembly design repository](https://github.com/WebAssembly/design)

first, so that this spec repository can remain focused. And please follow the

[guidelines for contributing](Contributing.md).
