How is this supposed to be used?

I read through the code and it seems sound, but is there a recommended way to use this?

- Publish the worker template
- Do a get from the client-side to the down route and specify the number of bytes to test?

The issue identifies the worker template, a client-side GET to the down route, and a byte-count parameter. Start by reading the repository's JavaScript entry points and tracing that request flow. Done means documenting the recommended usage steps and clarifying how the byte count should be specified.
