+This folder contains prebuilt browser versions of [protobuf.js](https://github.com/dcodeIO/protobuf.js)'s runtime for statically generated code. When sending pull requests, it is not required to update these.
+
+**NOTE:** The static code runtime includes just the bare minimum required to work with statically generated modules - and *nothing else*. Where applicable, it can be used as a drop-in replacement for the full library as it has the same general structure.
