+# 128-bit arithemtic proposal for WebAssembly.
+
+This repository is a clone of
+[`WebAssembly/spec`](https://github.com/WebAssembly/spec/). It is meant for
+discussion, prototype specification, and implementation of a proposal to add
+support for 128-bit arithmetic instructions for WebAssembly.
+
+* See the [overview](./proposals/128-bit-arithmetic/Overview.md) for a
+  high-level summary and rationale of the proposal.
+
+Original README from upstream repository follows...
